Hydrogenophaga sp. NT-26
-
arsenite + acceptor + H2O = arsenate + reduced acceptor
reaction mechanism, the catalytic Cys12, located at the active site, forms a covalent adduct with arsenate, the complex shows tetrahedral geometry, arsenite binds to Cys12 in a thiarsahydroxy adduct
-
arsenite + acceptor + H2O = arsenate + reduced acceptor
the catalytic Cys12 of the wild-type enzyme, located at the active site and surrounded by the Arg triad with Arg60, Arg94, and Arg107, forms a unique monohydroxyl Cys12-thiol-arsenite adduct with a positive charge on the arsenic, which is an unstable intermediate
