A proposed model for substrate binding to T. thermophilus DDGDH. (a) Chemical structures of citrate, 2,5-diketo-3-deoxygluconate (DDG) and 2-keto-3-deoxygluconate (KDG). (b) Stereoview (modelled) of the binding of citrate and NAD+ to DDGDH. (c) Stereoview (modelled) of the binding of 2-keto-3-deoxygluconate to NAD-dependent DDGDH. Ser129, Tyr144 and Lys148 in this figure constitute the catalytic triad in T. thermophilus DDGDH.
