4HBT

4HBT
PFAM accession number:PF03061
Interpro abstract (IPR006683):

A wide variety of enzymes contain this domain, principally thioesterases. Proteins containing this domain include 4HBT (4-hydroxybenzoyl-CoA thioesterase) (EC 3.1.2.23) which catalyses the final step in the biosynthesis of 4-hydroxybenzoate from 4-chlorobenzoate in the soil dwelling microbe Pseudomonas CBS-3 [(PUBMED:9837940), (PUBMED:1610806)]. It also includes various cytosolic long-chain acyl-CoA thioester hydrolases. Long-chain acyl-CoA hydrolases hydrolyse palmitoyl-CoA to CoA and palmitate, they also catalyse the hydrolysis of other long chain fatty acyl-CoA thioesters [(PUBMED:8805534)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry 4HBT
