Phospholipase B1: Lysates

Membrane-associated phospholipase. Exhibits a calcium-independent broad substrate specificity includingphospholipase A2/lysophospholipase activity. Preferential hydrolysis at the sn-2 position of diacylphospholipids anddiacyglycerol, whereas it shows no positional specificity toward triacylglycerol. Exhibits also esterase activitytoward p-nitrophenyl. May act on the brush border membrane to facilitate the absorption of digested lipids (Bysimilarity)
