The electron density in the active sites of subunits A and D could be interpreted as either tartrate or glyceraldehyde-3-phosphate, or as a mixture. The model has been built conservatively with tartrate bound. The electron density in the active site of subunit C appeared consistent with the formation of a covalently bound species and a number of mechanistically plausible ligands were modelled. Of the potential structures tested, the enol(ate)-ThDP species was judged most consistent with the experimental data, however other possibilities exist and the model should be treated with due caution.
