G117H MUTANT OF HUMAN BUTYRYLCHOLINESTERASE IN COMPLEX WITH ECHOTHIOPHATEG117H MUTANT OF HUMAN BUTYRYLCHOLINESTERASE IN COMPLEX WITH ECHOTHIOPHATE
Template:ABSTRACT PUBMED 21091433
DiseaseDisease
[CHLE_HUMAN] Defects in BCHE are the cause of butyrylcholinesterase deficiency (BChE deficiency) [MIM:177400]. BChE deficiency is a metabolic disorder characterized by prolonged apnoea after the use of certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anesthetics. The duration of the prolonged apnoea varies significantly depending on the extent of the enzyme deficiency. BChE deficiency is a multifactorial disorder. The hereditary condition is transmitted as an autosomal recessive trait.
FunctionFunction
[CHLE_HUMAN] Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.[1][2]
