3.1.1.116

Accepted name:

sn-1-specific diacylglycerol lipase

Reaction:

a 1,2-diacyl-sn-glycerol + H₂O = a 2-acylglycerol + a fatty acid

Other name(s):

DAGLA (gene name); DAGLB (gene name)

Systematic name:

diacylglycerol sn-1-acylhydrolase

Comments:

The enzyme, present in animals, is specific for the sn-1 position. When acting on 1-acyl-2-arachidonoyl-sn-glycerol, the enzyme forms 2-arachidonoylglycerol, the most abundant endocannabinoid in the mammalian brain.
