Protein Family Models

This family contains a wide variety of enzymes, principally thioesterases. This family includes 4HBT (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. This family 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. [1]. 9837940.

TIGR00369 describes a set of hotdog fold thioesterases, found either as stand-alone protein or as a domain of a multifunctional protein. Examples include EntH (the proofreading thioesterase of enterobactin biosynthesis), MenI (1,4-dihydroxy-2-naphthoyl-CoA hydrolase), and PaaI (hydroxyphenylacetyl-CoA thioesterase).
