EC 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.
