Structure of S. cerevisiae GPD1. Left: the dimer found in the asymmetric unit and the biologically active form of the enzyme. The A subunit is shown in blue and the B subunit is shown in green. The N-terminal domain (N-term) and C-terminal domain (C-term) are labelled. NAD+ molecules are coloured red and their locations are deduced from the binding site in the human enzyme (PDB entry 1x0v). Right: the A subunit rotated by 90° to provide a better view of the substrate-binding cleft. |
