Phospholipase A
Encyclopedia
Phospholipase A can refer to:
An enzyme that displays both phospholipase A1 and phospholipase A2 activities is called a Phospholipase B
(see main article on phospholipase
s).
- Phospholipase A1Phospholipase A1Phospholipase A1 is a phospholipase enzyme which removes the 1-acyl. Phospholipase A1 is a component of snake venom, but it also serves in normal metabolism to produce fatty acids from phospholipids. In melanocytic cells the Phospholipase A1 gene may be regulated by MITF.-External links:*...
- Phospholipase A2Phospholipase A2Phospholipases A2 are enzymes that release fatty acids from the second carbon group of glycerol. This particular phospholipase specifically recognizes the sn-2 acyl bond of phospholipids and catalytically hydrolyzes the bond releasing arachidonic acid and lysophospholipids...

Phospholipase B
Phospholipase B 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 ....

Phospholipase
A phospholipase is an enzyme that hydrolyzes phospholipids into fatty acids and other lipophilic substances. There are four major classes, termed A, B, C and D, distinguished by the type of reaction which they catalyze:*Phospholipase A...
