 23-138 1.22e-22

PaaI_thioesterase is a tetrameric acyl-CoA thioesterase with a hot dog fold and one of several proteins responsible for phenylacetic acid (PA) degradation in bacteria. Although orthologs of PaaI exist in archaea and eukaryotes, their function has not been determined. Sequence similarity between PaaI, E. coli medium chain acyl-CoA thioesterase II, and human thioesterase III suggests they all belong to the same thioesterase superfamily. The conserved fold present in these thioesterases is referred to as an asymmetric hot dog fold, similar to those of 4-hydroxybenzoyl-CoA thioesterase (4HBT) and the beta-hydroxydecanoyl-ACP dehydratases (FabA/FabZ).

Thioesterase superfamily; This family contains a wide variety of enzymes, principally thioesterases. This family includes 4HBT (EC 3.1.2.23) which catalyzes 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 catalyze the hydrolysis of other long chain fatty acyl-CoA thioesters.

 52-137 1.36e-07

The hotdog fold was initially identified in the E. coli FabA (beta-hydroxydecanoyl-acyl carrier protein (ACP)-dehydratase) structure and subsequently in 4HBT (4-hydroxybenzoyl-CoA thioesterase) from Pseudomonas. A number of other seemingly unrelated proteins also share the hotdog fold. These proteins have related, but distinct, catalytic activities that include metabolic roles such as thioester hydrolysis in fatty acid metabolism, and degradation of phenylacetic acid and the environmental pollutant 4-chlorobenzoate. This superfamily also includes the PaaI-like protein FapR, a non-catalytic bacterial homolog involved in transcriptional regulation of fatty acid biosynthesis.
