Crystal Structure of ArsH from Sinorhizobium meliloti
|
Overview
Purified ArsH from Sinorhizobium meliloti exhibits NADPH:FMN-dependent, reduction of molecular O2 to hydrogen peroxide and catalyzes reduction of, azo dyes. The structure of ArsH was determined at 1.8A resolution. ArsH, crystallizes with eight molecules in the asymmetric unit forming two, tetramers. Each monomer has a core domain with a central five-stranded, parallel beta-sheet and two monomers interact to form a classical, flavodoxin-like dimer. The N- and C-terminal extensions of ArsH are, involved in interactions between subunits and tetramer formation. The, structure may provide insight in how ArsH participates in arsenic, detoxification.
