Orphan date April 2012 Peptide computing is a form of computing which uses peptide s and molecular biology , instead of traditional silicon based computer technologies. The basis of this computational model is the affinity of antibodies towards peptide sequences. Similar to DNA computing , the parallel interactions of peptide sequences and antibodies have been used by this model to solve a few NP complete problems. Specifically, the hamiltonian path problem HPP and some versions of the set cover problem are a few NP complete problems which have been solved using this computational model so far. This model of computation has also been shown to be Turing completeness computationally universal or Turing complete . This model of computation has some critical advantages over DNA computing . For instance, while DNA is made of four building blocks, peptide s are made of twenty building blocks. The peptide antibody interactions are also more flexible with respect to recognition and affinity than an interaction between a DNA strand and its reverse complement. However, unlike DNA computing, this model is yet to be practically realized. The main limitation is the availability of specific monoclonal antibodies required by the model.

A peptide library is a newly developed technique for protein related study. A peptide library contains a great number of peptides that have a systematic combination of amino acids . Usually, peptide library is synthesized on solid phase, mostly on resin , which can be made as flat surface or beads. The peptide library provides a powerful tool for drug design , protein protein interactions , and other biochemical as well as pharmaceutical applications. You can create a mix of desired amino acids at each point in a sequence. In this way, you could create a library of 20 different polypeptides with only one amino acid residue at random and the rest being the same. usefulness of this form of peptide synthesis is limited as you can t go beyond 70 peptides in length. This would give you 70 20 possible combinations and that s only if you don t include the plethora of available amino acids with pre installed post translational modifications. Most drug development does not involve such a random assortment of proteins as you wouldn t learn very much. Important example. Say you wanted a peptide chain 10 residues in length to use in native chemical ligation with a larger recombinantly expressed protein. Chosen out of complete randomness you want a set of proteins with the following. residue 1 Alanine only residue 2 glutamine, glycine, arginine, glutamic acid, serine, or methionine residue 3 any one of all 20 amino acids residue 4 acetyl lysine only residue 5 alanine residue 6 isoleucine residue 7 aspartic acid residue 8 phenylalanine residue 9 acetyl lysine residue 10 argineine with the carboxy terminal thioester. there would be 20 different proteins at residue 3. each one of those would .... this peptide library would be useful for analyzing the effect of the post translational modification ... formula, if you made a completely random peptide library with n amino acids for each link in the chain ...

Orphan date April 2012 Peptide amphiphile s are peptide based molecules that self assemble into high aspect ratio nanofibers. They were first described by the group of Samuel I. Stupp at Northwestern University in 2003. These molecules typically have three regions a hydrophobic tail, a region of beta sheet forming amino acids, and a peptide epitope designed to allow solubility of the molecule in water, perform a biological function by interacting with living systems, or both. Self assembly occurs by the combination of hydrogen bonding between beta sheet forming amino acids and hydrophobic collapse of the tails to yield the formation of cylindrical micelles that present the peptide epitope at extremely high density at the nanofiber surface. This self assembly of molecules into fibers occurs spontaneously in all solutions of peptide amphiphiles, which have a vanishingly small critical micelle concentration. By changing pH or adding counterions to screen the charged surfaces of fibers, gels can be formed. It has been shown that injection of peptide amphiphile solutions in vivo leads to in situ gel formation due to the presence of counterions in physiological solutions. This, along with the complete biodegradability of the materials, suggests numerous applications in in vitro and in vivo ... to this, peptide amphiphiles can be used to form more sophisticated architectures.

Bis peptides are analogues of peptide s, but consist of bis amino acid s, which bear two carboxyl group s and two amino group s. The connection of specific bis amino acids leads to the formation of bis peptides with well defined molecular shape, which is of great interest for designing nano structures. Possible applications that are currently investigated, include the binding and inactivation of cholera toxin and the cross linkage of surface protein s of various viruses HIV , Ebola virus . Further the group of Christian Schafmeister developed molecular hinges, which can be used for the construction of molecular machine s, such as nano valve s or data storage device data storage systems.

nofootnotes date March 2011 Orphan date August 2010 Image WALP 19.png thumb 280px WALP 19 protein peptide of the following sequence of 19 amino acids GWWLALALALALALALWWA. Tryptophan residues are shown in green while leucines and alanines are displayed in red and blue, respectively. WALP peptides are a class of synthesized, membrane spanning Alpha helix helices composed of tryptophan W , alanine A , and leucine L amino acids. They are designed to study properties of proteins in lipid membranes such as orientation, extent of insertion, and hydrophobic mismatch . Significance The transmembrane region of many integral membrane proteins consists of at least one alpha helix, which can directly affect cell signaling and molecular transport across the bilayer. The hydrophobic environment of the phospholipid tails affects the position and structure of such domains and thus may influence protein function. The bilayer can change the thickness of its hydrocarbon region to interact optimally with hydrophobic regions of a transmembrane protein, such as a WALP. WALPs provide an effective model for studying such interactions because of their hydrophobic, alternating alanine and leucine regions. They are readily manipulated by extending or decreasing the number of amino acids and by substituting the anchoring tryptophan residues for charged residues, such as arginine and lysine. Additionally, they are useful for studying the impact of changes in lipid composition on peptide insertion. Responses to lipid environment When hydrophobic mismatch occurs, WALPs are known to tilt in the bilayer. The extent of this tilt is affected up to a certain point by an entropy contribution that arises from the helix s presence in the bilayer and then by more specific helix lipid interactions. When charged residues are substituted for the anchoring residues, these charged amino acids prefer a higher position ... pmc 2895360 Reflist External links http www.example.com example.com DEFAULTSORT Walp Peptide Category ... more details

Introduction Porcine intestinal spirochaetosis is a Notifiable disease notifiable pig disease caused by the bacterium Brachyspira pilosicoli . Infection causes mild gastrointestinal signs in young pigs and intestinal spirochetosis in humans , as it is a zoonosis . The disease is widespread in pig rearing countries and may be referred to as PIS, Spirochaetal Diarrhoea and Porcine Colonic Spirochaetosis . Clinical Signs & Diagnosis Clinical signs are most commonly seen in young pigs aged 8 14 weeks . Normally a greyish diarrhoea is seen in individual piglets, and poor growth rates and Feed conversion ratio feed conversion ratios are observed on a herd level. Stress, caused by moving and mixing groups of piglets can increase incidence. A definitive diagnosis can be made by Bacterial culture culturing the bacterium on a specific Agar plate blood agar medium, followed by PCR . Alternatively, Autopsy postmortem and Histology histological examination of the large intestine can confirm the diagnosis. Treatment & Control Antibiotics are the treatment of choice. They should be administered by injection or water. Pig husbandry measures should be employed to ensure that stressors such as the mixing and moving of pigs are kept to a minimum to reduce disease incidence.
