This family consists of various acyl-acyl carrier protein (ACP) thioesterases (TE) these terminate fatty acyl group extension via hydrolysing an acyl group on a fatty acid [1]. These proteins are usually composed of a pair of tandem HotDog domains. This entry represents the N-terminal one of the pair.
