WebAug 23, 2005 · Structure analysis of bacterial NATs revealed a Cys-His-Asp catalytic triad that is strictly conserved in all known NATs. Previously, we have demonstrated by kinetic and isotope effect studies that acetylation of the hamster NAT2 is dependent on a thiolate-imidazolium ion pair (Cys-S(-)-His-ImH(+)) and not a general acid-base catalysis.

Ser-His-Asp The Serine-Histidine-Aspartate motif is one of the most thoroughly characterised catalytic motifs in biochemistry. The triad is exemplified by chymotrypsin, a model serine protease from the PA superfamily which uses its triad to hydrolyse protein backbones. The aspartate is hydrogen bonded … See more A catalytic triad is a set of three coordinated amino acids that can be found in the active site of some enzymes. Catalytic triads are most commonly found in hydrolase and transferase enzymes (e.g. proteases See more Enzymes that contain a catalytic triad use it for one of two reaction types: either to split a substrate (hydrolases) or to transfer one portion of a … See more Nucleophile The side-chain of the nucleophilic residue performs covalent catalysis on the substrate. … See more The enzymology of proteases provides some of the clearest known examples of convergent evolution. The same geometric arrangement of triad residues occurs in over 20 separate enzyme superfamilies. Each of these superfamilies is the result of convergent … See more The enzymes trypsin and chymotrypsin were first purified in the 1930s. A serine in each of trypsin and chymotrypsin was identified as the catalytic nucleophile (by diisopropyl fluorophosphate modification) … See more The sophistication of the active site network causes residues involved in catalysis (and residues in contact with these) to be highly See more • Biology portal • Active site • Convergent evolution • Divergent evolution See more Web杭州专肽生物技术有限公司是一家集多肽的研发、生产、销售为一体的专业多肽合成公司，主要产品有、十三肽KPGHMYQNEDYLC、、、H2N-KPGHMYQNEDYLC-OH、H2N-Lys-Pro-Gly-His-Met-Tyr-Gln-Asn-Glu-Asp-Tyr-Leu-Cys-COOH,多肽 WebNational Center for Biotechnology Information greenheart solar
