Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 3.1.1.23

Enzymes and Genes:

Arabidopsis thaliana col : acylhydrolase Inferred from experiment : DSEL
Saccharomyces cerevisiae : monoacylglycerol lipase Inferred from experiment : YJU3

In Pathway: triacylglycerol degradation

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

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.

Instance reaction:
1-oleoyl-sn-glycerol + H2O → glycerol + oleate + H+ (3.1.1.23)

Enzyme Commission Primary Name: acylglycerol lipase

Enzyme Commission Synonyms: monoacylglycerol lipase, monoacylglycerolipase, monoglyceride lipase, monoglyceride hydrolase, fatty acyl monoester lipase, monoacylglycerol hydrolase, monoglyceridyllipase, monoglyceridase
