proteins similar to putative ester hydrolase C11orf54/PTD012
The structure of this domain displays an alpha-beta-beta-alpha four layer topology, with an HxHxxxxxxxxxH motif (x could be any residue) that coordinates a zinc ion, and an acetate anion at a site that may support the enzymatic activity of a ester. In vitro hydrolytic activity towards para-nitrophenylacetate for the human enzyme was reported. The proteins are homologous to bacterial alpha-acetolactate decarboxylase (AldB, E.C. 4.1.1.5), which converts acetolactate into acetoin.
