Disease
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.
Function
CHLE_HUMAN Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.[1] [2]
Publication Abstract from PubMed
The multifunctional nature of Alzheimer's disease calls for multi-target directed ligands (MTDLs) able to act on different components of the pathology, like the cholinergic dysfunction and amyloid aggregation. Such MTDLs are usually based on cholinesterase inhibitors (e.g., tacrine or huprine) coupled to another active molecule aimed at a different target. To aid in the design of these MTDLs we report the crystal structures of human acetylcholinesterase (hAChE) in complex with FAS-2 and a hydroxylated derivative of huprine (huprine W), and of human butyrylcholinesterase (hBChE) in complex with tacrine. Huprine W in hAChE and tacrine in hBChE reside in strikingly similar positions highlighting the conservation of key interactions, namely, pi-pi/cation-pi interactions with Trp86(82), and hydrogen bonding with the main chain carbonyl of the catalytic histidine. Huprine W forms additional interactions with hAChE which explains its superior affinity: the isoquinoline moiety is associated with a group of aromatic residues (Tyr337, Phe338 and Phe295 not present in hBChE) in addition to Trp86; the hydroxyl group is hydrogen bonded to both the catalytic serine and residues in the oxyanion hole; and the chlorine substituent is nested in a hydrophobic pocket interacting strongly with Trp439. There is no pocket in hBChE able to accommodate the chlorine substituent.
