CRYSTAL STRUCTURE OF A TOLUENE 4-MONOOXYGENASE CATALYTIC EFFECTOR PROTEIN VARIANT MISSING TEN N-TERMINAL RESIDUES (DELTA-N10 T4MOD)

Overview

Toluene 4-monooxygenase (T4MO) is a four-component complex that catalyzes, the regiospecific, NADH-dependent hydroxylation of toluene to yield, p-cresol. The catalytic effector (T4moD) of this complex is a 102-residue, protein devoid of metals or organic cofactors. It forms a complex with the, diiron hydroxylase component (T4moH) that influences both the kinetics and, regiospecificity of catalysis. Here, we report crystal structures for, native T4moD and two engineered variants with either four (DeltaN4-) or 10, (DeltaN10-) residues removed from the N-terminal at 2.1-, 1.7-, and 1.9-A, resolution, respectively. The crystal structures have C-alpha, root-mean-squared differences of less than 0.8 A for the central core, consisting of residues 11-98, showing that alterations of the ... [(full description)]
