    Protein Summary

    The gene KT2440 (NP_742468.1) from Pseudomonas putida encodes a putative 4-hydroxybenzoyl-CoA thioesterase (4HBT) EC:, a member of thioesterase superfamily PF03061.  The enzyme belongs to the class of alpha and beta (a+b) proteins and adopts a thioesterase/thiol ester dehydrase-isomerase fold type SCOP54636.  The enzyme catalyzes the following reaction: 4-hydroxybenzoyl-CoA + H(2)O <=> 4-hydroxybenzoate + CoA.  This is the final step of the 4-chlorobenzoate degradation pathway.   The biological form of 4HBT is a homotetramer with four active sites.  Each subunit of the 4HBT tetramer adopts a so-called hot-dog fold similar to those of beta-hydroxydecanoyl-ACP dehydratase, (R)-specific enoyl-CoA hydratase, and type II, thioesterase (TEII).  Several structures of the enzyme homologues a from different Pseudomonas sp. strain have been solved: 1LO8 1LO7.
