homology modeling of enzyme CAT structures using the crystal structure of Escherichia coli CAT, PDB ID 3CLA, overview. Residue A138 resides on beta-sheet 7 and is located on the protein surfaces far from the active center. Although the side chains of I134, P135, and L164 surround this residue, no hydrophobic interactions are observed within 4 A. Modeling of CATA138T, overview |

 2.3.1.28 | more |
pentapeptide insertion mutagenesis is used to identify regions of CATI that are tolerant or intolerant of peptide insertions. The latter pinpoints regions that may be suitable for the design of ligands that block CATI function, whereas the former reveals sites in which peptides or entire proteins may be introduced for the design of bifunctional CATI enzymes |

 2.3.1.28 | physiological function |
chloramphenicol acetyltransferase type C CAT or CATC is found in Vibrio parahaemolyticus and its closely related species Vibrio alginolyticus, Vibrio antiquarius , and Vibrio diabolicus. Naturally occurring variants of CATC can confer diverse resistance levels against chloramphenicol in Escherichia coli. The enzyme kinetics of CATC variant proteins supports the diversity of their resistance phenotypes |
