Phospholipase-B_like. This subgroup of the SGNH-family of lipolytic enzymes may have both esterase and phospholipase-A/lysophospholipase activity. It's members may be involved in the conversion of phosphatidylcholine to fatty acids and glycerophosphocholine, perhaps in the context of dietary lipid uptake. Members may be membrane proteins. The tertiary fold of the SGNH-hydrolases is substantially different from that of the alpha/beta hydrolase family and unique among all known hydrolases; Its active site closely resembles two of the three components of typical Ser-His-Asp(Glu) triad from other serine hydrolases.
