S. aureus Trx structure and kinetic values of indicated variants. (A) The Trx structure (taken from (29)) is shown in the cartoon representation with the highlighted residues. Trp28 forms an H bond with Asp58 and participates in deprotonation of Cys29 to form the active thiolate. The oxidized Trx with a Cys29—Cys32 disulfide bond is shown. (B) The reaction velocities of the Trx enzymes Trp28 (WT), Bta28 and Ala28 are plotted against the substrate concentration of oxidized ArsC.
