Unreferenced date December 2009 In chemistry , a trimer is a chemical reaction product derived from three identical precursors. Trimers are typically cyclic. Chemical compounds that often trimerise are aliphatic isocyanate s and cyanic acid s. Often, trimerization competes with polymerization. In the Reppe synthesis , the trimerization of acetylene gives benzene Image Reppe chemistry benzene.png 240px Another example is the procedure of production of polymer s. At first, a monomer is made. By combining two monomers, a dimer chemistry dimer is produced.

UvrABC endonuclease is a multienzyme complex in Escherichia coli E.coli bacteria involved in DNA repair mechanism by nucleotide excision repair , and it is, therefore, sometimes called an excinuclease . This UvrABC repair process, sometimes called the short patch process, involves the removal of 12 nucleotides where a genetic mutation has occurred followed by a DNA polymerase, replacing these aberrant nucleotides with the correct nucleotides and completing the DNA repair . This enzyme complex is able to repair many different types of damage, including cyclobutyl dimer formation. Mechanism Two UvrA proteins form a dimer and they both have ATPase GTPase activity. The UvrA protein dimer dimer binds with UvrB and forms a protein trimer trimer that is able to detect DNA damage .The UvrA dimer functions as the unit responsible for the detection of DNA damage, probably through a mechanism of detecting distortions in the DNA double helix . The UvrB part of the trimer attaches to the double helix at the damaged site. The UvrA dimer leaves and a UvrC protein comes in and binds to the UvrB monomer and, hence, forms a new UvrBC dimer. This dimer is responsible for cleaving the nucleotides either side of the DNA damage. UvrB cleaves a phosphodiester bond 4 nucleotides downstream of the DNA damage, and the UvrC cleaves a phosphodiester bond 8 nucleotides upstream of the DNA damage and created 12 nucleotide excised segment. DNA helicase II sometimes called UvrD then comes in and removes the excised segment by removing the base pairing. The UvrB still remains in place even though UvrC has disassociated at this stage, as UvrB may be involved to prevent the reannealing of the excised DNA. DNA polymerase I comes in and fills in the correct nucleotides sequence, kicking off UvrB in the process, and the last phosphodiester bond is completed by DNA ligase.

The 240 copies of the hexon Trimer biochemistry trimer that are produced are organised so that 12 lie on each of the 20 facets. The central 9 hexons in a facet are cemented together by 12 copies of polypeptide IX. The penton complex, formed by the peripentonal hexons and base hexon holding in place a fibre , lie at each of the 12 vertices. ref name pmid7932702 cite journal author Athappilly FK, Murali R, Rux JJ, Cai Z, Burnett RM title The refined crystal structure of hexon, the major coat protein of adenovirus type 2, at 2.9 A resolution journal J.

Within a hexon trimer, the protein domains domains are arranged around a pseudo 6 fold axis. The Domain biology domain s have a beta sandwich secondary structure structure consisting of 8 strands in two beta sheet sheets with a jelly roll topology each domain is heavily decorated with many insertions. ref name pmid12915569 cite journal author Rux JJ, Kuser PR, Burnett RM title Structural and phylogenetic analysis of adenovirus hexons by ... more details
