9.B.371. The PaaI Thioesterase (PTE) Family
These proteins are small (usually around 130 - 200 aas in length with 0 - 3 putative TMSs. They are annotated either as PaaI thioesterases or hydroxyphenylacetyl-CoA thioesterases or acyl-CoA thioesterases or hotdog-fold thioesterases. These proteins, listed as a subfamily with TC# 9.B.371.1, are distantly related to another subfamily with TC# 9.B.371.2.
