EC Number: 220.127.116.11
Note that this reaction equation differs from the official Enzyme Commission reaction equations for this EC number.
Reaction Locations: periplasmic space (sensu Gram-negative Bacteria)
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: phospholipase A2
Enzyme Commission Synonyms: lecithinase A, phosphatidase, phosphatidolipase, phospholipase A
Enzyme Commission Summary:
Also acts on phosphatidylethanolamine, choline plasmalogen and phosphatides, removing the fatty acid attached to the 2-position. Requires Ca2+.
