Flexibility in substrate binding at the GAPDH active site (stereo). Position of D-G3H in the CpGAPDH ternary complex subunit A (yellow), subunit D (wheat); mutant BsGAPDH ternary complex (PDBId: 1nqo) subunit O (pale cyan); BsGAPDH thiacyl intermediate (PDBId: 3cmc) subunit O (light green); E. coli GAPDH (1dc4) subunit O (light pink). The 'Ps' and 'new Pi' sites are indicated. A sulfate ion is bound in each subunit of the BsGAPDH complex.
