X‑ray Diffraction and Density Functional Theory Provide Insight into Vanadate Binding to Homohexameric Bromoperoxidase II and the Mechanism of Bromide Oxidation
X-ray
diffraction of native bromoperoxidase II (EC 1.11.1.18) from
the brown alga <i>Ascophyllum nodosum</i> reveals at a resolution
of 2.26 Å details of orthovanadate binding and homohexameric
protein organization. Three dimers interwoven in contact regions and
tightened by hydrogen-bond-clamped guanidinium stacks along with regularly
aligned water molecules form the basic structure of the enyzme. Intra-
and intermolecular disulfide bridges further stabilize the enzyme
preventing altogether the protein from denaturing up to a temperature
of 90 °C, as evident from dynamic light scattering and the on-gel <i>ortho</i>-dianisidine assay. Every monomer binds one equivalent
of orthovanadate in a cavity formed from side chains of three histidines,
two arginines, one lysine, serine, and tryptophan. Protein binding
occurs primarily through hydrogen bridges and superimposed by Coulomb
attraction according to thermochemical model on density functional
level of theory (B3LYP/6-311++G**). The strongest attractor is the
arginine side chain mimic <i>N</i>-methylguanidinium, enhancing
in positive cooperative manner hydrogen bridges toward weaker acceptors,
such as residues from lysine and serine. Activating hydrogen peroxide
occurs in the thermochemical model by side-on binding in orthovanadium
peroxoic acid, oxidizing bromide with virtually no activation energy
to hydrogen bonded hypobromous acid
