TAURINE/ALPHA-KETOGLUTARATE DIOXYGENASE FROM ESCHERICHIA COLI

Overview

Taurine/alpha-ketoglutarate dioxygenase (TauD), a non-heme Fe(II), oxygenase, catalyses the conversion of taurine (2-aminoethanesulfonate) to, sulfite and aminoacetaldehyde concurrent with the conversion of, alpha-ketoglutarate (alphaKG) to succinate and CO(2). The enzyme allows, Escherichia coli to use taurine, widely available in the environment, as, an alternative sulfur source. Here we describe the X-ray crystal structure, of TauD complexed to Fe(II) and both substrates, alphaKG and taurine. The, tertiary structure and fold of TauD are similar to those observed in other, enzymes from the broad family of Fe(II)/alphaKG-dependent oxygenases, with, closest structural similarity to clavaminate synthase. Using the TauD, coordinates, a model was determined for the closely related enzyme, ... [(full description)]
