General annotation (Comments)

Function

Hydrolyzes all ester bonds in triglyceride and displays a high affinity for triolein. For unsaturated substrates having long fatty acyl chains (C18:2 cis-9, cis-12 and C18:3 cis-9, cis-12, cis-15) GCL I shows higher specific activity than GCL II, whereas GCL II shows higher specific activity against saturated substrates having short fatty acid chains (C8, C10, C12 and C14).

Catalytic activity

Triacylglycerol + H2O = diacylglycerol + a carboxylate.

Subunit structure

Monomer.

Subcellular location

Secreted.

Sequence similarities

Belongs to the type-B carboxylesterase/lipase family.
