(a) Hydrogen-bond interaction of the N-terminal histidine residue of Rv1264 with the substrate-specifying residues. (b) Active (blue) and inactive (yellow–orange) forms of Rv1264. The subunit which moves from the inactive state to the active state is shown with 60% transparency. The arrows show the switch elements α1-switch and αN10-switch of the active and inactive forms, which are highlighted in darker shades.
