Structural biology is a branch of molecular biology , biochemistry , and biophysics concerned with the molecular structure of biological macromolecule s, especially protein s and nucleic acid s, how they acquire the structures they have, and how alterations in their structures affect their function. This subject is of great interest to biologists because macromolecules carry out most of the functions of cell biology cells , and because it is only by coiling into specific three dimensional shapes that they are able to perform these functions. This architecture, the tertiary structure of molecules, depends in a complicated way on the molecules basic composition, or primary structure s. File Hemoglobin t r state ani.gif thumb Hemoglobin , the oxygen transporting protein found in red blood cells Biomolecule s are too small to see in detail even with the most advanced light microscope s.

There are three classes of proteins with HEPN domains Single domain HEPN protein proteins found in many bacteria. Two domain proteins with N terminal nucleotidyltransferase NT and C terminal HEPN protein domain domains . This N terminal NT domain belongs to a large family of NTs, which includes several classes of enzyme s that are responsible for some types of bacteria bacterial resistance to aminoglycosides . These enzymes deactivate various antibiotic s by transferring a nucleotidyl group to the drug. A multidomain sacsin protein in genomes of fish and mammal s. The HEPN domain is located at the C terminus of the protein, directly after the DnaJ domain. The crystal structure of the HEPN domain from the TM0613 protein of Thermotoga maritima indicates that it is structurally similar to the C terminal all alpha helical domain of kanamycin nucleotidyltransferase kanamycin nucleotidyltransferases KNTases . It is composed of five alpha helices, three of which form an up and down helical bundle, with a pair of short Alpha helix helices on the side.

Context date February 2009 Confusing date September 2007 In biology and in science in general a mechanism is a complex object system or, more generally, a Process science process that produces a regular phenomenon. For example, natural selection is one of the mechanisms of biological evolution , other being genetic drift , biased mutation, and gene flow competition , predation , Parasitism host parasite interactions , etc. are mechanisms of Community ecology community structuring and membrane depolarization is the mechanism of Action potential transmission of neural signals . Accordingly, descriptions of mechanisms are a part of an answer to a question about why some object or process occurred. In other words, descriptions of mechanisms occur in explanations of biological facts. Thus, mechanism refers back from the object or process, along some chain of causation. No description of mechanism is ever complete. For example, the mechanism of sunlight might include the rotation of the earth, the Earth s orbit, the sun, nuclear reactions, heat, temperature, radiation emission, electromagnetic theory about the propagation of light, formation of the solar system, etc. Compare this to the Function biology function of the object or process, which looks forward along some chain of causation ... of science biology have been provided in the past decades.
