STUCTURE OF THE ARSENATED DE NOVO DESIGNED PEPTIDE COIL SER L9C
Overview
Arsenic, a contaminant of water supplies worldwide, is one of the most, toxic inorganic ions. Despite arsenic's health impact, there is relatively, little structural detail known about its interactions with proteins., Bacteria such as Escherichia coli have evolved arsenic resistance using, the Ars operon that is regulated by ArsR, a repressor protein that, dissociates from DNA when As(III) binds. This protein undergoes a critical, conformational change upon binding As(III) with three cysteine residues., Unfortunately, structures of ArsR with or without As(III) have not been, reported. Alternatively, de novo designed peptides can bind As(III) in an, endo configuration within a thiolate-rich environment consistent with that, proposed for both ArsR and ArsD. We report the structure of the ... [(full description)]
