yrhL-like subfamily of SGNH-hydrolases, 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. Most members of this sub-family appear to co-occur with N-terminal acyltransferase domains. Might be involved in lipid metabolism.
