HUMAN MONOAMINE OXIDASE B: I199F MUTANT IN COMPLEX WITH ISATIN
Overview
Several reversible inhibitors selective for human monoamine oxidase B (MAO, B) that do not inhibit MAO A have been described in the literature. The, following compounds: 8-(3-chlorostyryl)caffeine, 1,4-diphenyl-2-butene, and trans,trans-farnesol are shown to inhibit competitively human, horse, rat, and mouse MAO B with K(i) values in the low micromolar range but are, without effect on either bovine or sheep MAO B or human MAO A. In, contrast, the reversible competitive inhibitor isatin binds to all known, MAO B and MAO A with similar affinities. Sequence alignments and the, crystal structures of human MAO B in complex with 1,4-diphenyl-2-butene or, with trans,trans-farnesol provide molecular insights into these, specificities. These inhibitors span the substrate and entrance cavities, ... [(full description)]
