Close-up of the overlay of the CXXC center of the crystal structures of oxidized wild-type hBCATm (yellow ribbon with Cys315 and Cys318 in light gray) and the C318A/C315CSD mutant (blue ribbon with C315CSD and C318A in dark gray). The orientation of C315CSD resembles that of Cys315 in the disulfide-bonded form. (Atom color scheme: carbon, gray and light gray; oxygen, red; sulfur, yellow.) |
