The Michaelis–Menten-like complex and wtsAgu115A dimerization, with domains indicated and chains indicated by subscripts. (a) Secondary-structure representation of the wtsAgu115A dimer in complex with xylopentaose (orange) and Ca2+ (black spheres), (b) surface representation of the wtsAgu115A dimer in complex with xylopentaose (orange) and Ca2+ (black spheres) and (c) enlargement of the five visible sugar moieties of the xylohexaose (orange) with hydrogen bonds shown (yellow dotted lines) with their distances in Å. The subsites are indicated and named according to McKee et al. (2012). D-Xylopyranose moiety 901 corresponds to +2NR, 902 to +1NR, 903 to +1, 904 to +1R and 905 to +2R. |
