The crystal structure of the A(4) isoform of photosynthetic glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from Arabidopsis thaliana, expressed in recombinant form and complexed with NAD, is reported. The crystals, which were grown in 2.4 M ammonium sulfate and 0.1 M sodium citrate, belonged to space group I222. The asymmetric unit includes ten subunits, i.e. two independent tetramers plus a dimer that generates a third tetramer by a crystallographic symmetry operation. The crystal structure was solved by molecular replacement and refined to an R factor of 23.7% and an R(free) factor of 28.9% at 2.6 A resolution. In the final model, each subunit binds one NAD(+) molecule and two sulfates, which occupy the P(s) and the P(i) anion-binding sites. Detailed knowledge of this structure is instrumental for structural investigation of supramolecular complexes of A(4)-GAPDH, phosphoribulokinase and CP12, which are involved in the regulation of photosynthesis in the model plant A. thaliana.
