Phospholipase A can refer to:
*
Phospholipase A1
*
Phospholipase A2
The enzyme phospholipase A2 (EC 3.1.1.4, PLA2, systematic name phosphatidylcholine 2-acylhydrolase) catalyse the cleavage of fatty acids in position 2 of phospholipids, hydrolyzing the bond between the second fatty acid “tail” and the glyce ...

Outer membrane phospholipase A1
Outer membrane phospholipase A1 (OMPLA) is an acyl hydrolase with a broad substrate specificity (EC:3.1.1.32.) from the bacterial outer membrane. It has been proposed that Ser164 is the active site of the protein (UniProt )
This integral memb ...
An enzyme that displays both phospholipase A1 and phospholipase A2 activities is called a
Phospholipase B
Phospholipase B, also known as lysophospholipase, is an enzyme with a combination of both PLA1 and PLA2 activities; that is, it can cleave acyl chains from both the sn-1 and sn-2 positions of a phospholipid. In general, it acts on lysolecithin (whi ...
