Descriptions

Application

Delivers high catalytic activity, ideal for robust high-throughput screening assays including drug-drug interaction studies, and pharmacokinetic studies for evaluating pro-drugs and non-CYP pathways of elimination.

Carboxylesterase 1 isoform b human has been used in the reaction to convert Amplex red to resorufin in horse radish peroxidase and oxygen independent manner. It has also been used in the development of an emission ratiometric two-photon probe (SE1) for quantitation in situ.

Biochem/physiol Actions

Carboxylesterase (CE) is implicated in drug metabolism in liver and hepatic steatosis. Deficiency of CE in humans causes obesity, hyperlipidemia, insulin insensitivity, and cancer.

General description

Carboxylesterase 1 is a member of a large multigene carboxylesterase family. These enzymes are responsible for the hydrolysis of ester- and amide-bond-containing drugs such as cocaine and heroin. They also hydrolyze long-chain fatty acid esters and thioesters. This enzyme is known to hydrolyze aromatic and aliphatic esters and is necessary for cellular cholesterol esterification. It may also play a role in detoxification in the lung and/or protection of the central nervous system from ester or amide compounds.

Carboxylesterase (CE) belongs to serine hydrolase family. It is widely present in the human body. Five isoforms of carboxylesterase is present in humans. It is encoded by CES1 gene mapped to 16q22.2 in human chromosome.

Unit Definition
