SGNH_hydrolase subfamily, similar to the putative arylesterase/acylhydrolase from the rumen anaerobe Prevotella bryantii XynE. The P. bryantii XynE gene is located in a xylanase gene cluster. SGNH hydrolases are a diverse family of lipases and esterases. The tertiary fold of the enzyme is substantially different from that of the alpha/beta hydrolase family and unique among all known hydrolases; its active site closely resembles the Ser-His-Asp(Glu) triad found in other serine hydrolases.
