THE OXIDATION STATE OF THE FOLATE LIGAND IS UNCLEAR REMARK 3 FROM THE EXPERIMENTAL ELECTRON DENSITY MAPS. GIVEN THAT THE REMARK 3 CRYSTAL WAS PREPARED WITH NADPH PRESENT, THE LIGAND MAY BE A REMARK 3 MIXTURE OF FOLATE, 7,8-DIHYDROFOLATE, AND 5,6,7,8- REMARK 3 TETRAHYDROFOLATE. IN ADDITION, THE OCCUPANCY ASSIGNED TO FOLATE, REMARK 3 0.8, WAS CHOSEN SO THAT THE AVERAGE TEMPERATURE FACTOR FOR THE REMARK 3 PTERIDINE RING WAS SIMILAR TO SURROUNDING RESIDUES IN THE ACTIVE REMARK 3 SITE. ACCORDINGLY, THE NADPH MAY BE A MIXTURE WITH THE OXIDIZED REMARK 3 CO-FACTOR, NADP(+).
