Other name(s): ali-esterase; B-esterase; monobutyrase; cocaine esterase; procaine esterase; methylbutyrase; vitamin A esterase; butyryl esterase; carboxyesterase; carboxylate esterase; carboxylic esterase; methylbutyrate esterase; triacetin esterase; carboxyl ester hydrolase; butyrate esterase; methylbutyrase; α-carboxylesterase; propionyl esterase; nonspecific carboxylesterase; esterase D; esterase B; esterase A; serine esterase; carboxylic acid esterase; cocaine esterase
Systematic name: carboxylic-ester hydrolase
Comments: Wide specificity. The enzymes from microsomes also catalyse the reactions of EC (arylesterase), EC (lysophospholipase), EC (acetylesterase), EC (acylglycerol lipase), EC (acylcarnitine hydrolase), EC (palmitoyl-CoA hydrolase), EC (amidase) and EC (aryl-acylamidase). Also hydrolyses vitamin A esters.
