(2) THERE IS RESIDUAL DENSITY IN (FO-FC) DIFFERENCE FOURIER MAP AT THE MAGNESIUM SITES IN BOTH MOLECULES AND THE B-FACTOR FOR EACH MAGNESIUM ION IS UNUSUALLY LOW. THESE OBSERVATIONS SUGGEST THAT THIS MAGNESIUM SITE MAY BE PARTIALLY OCCUPIED BY A HEAVIER METAL ION IN THE PROTEIN CRYSTAL. (3) THE SIDE CHAINS OF THE FOLLOWING RESIDUES ARE NOT FULLY RESOLVED. THE UNRESOLVED SIDE CHAIN ATOMS ARE ASSIGNED AN OCCUPANCY OF 0.00 AND AN ARBITORY B-FACTOR OF 100.00: ARG-A-13 LYS-A-74 PHE-A-77 ARG-A-137 LYS-A-224 GLU-A-533 GLU-A-548 LYS-B-86 ARG-B-93 GLU-B-131 GLU-B-182 ARG-B-187 PHE-C-17 THR-C-18 ARG-C-19 GLU-C-69 LYS-C-74 ARG-C-521 GLU-C-533 LYS-D-86 LYS-D-89 GLU-D-131 HIS-D-284 (4) LIGANDS LABELLED AS TRD ARE ALL ALKYL CHAINS (WITH DIFFERENT LENGTHS) OF EITHER DMU OR NATIVE MEMBRANE LIPIDS SUCH AS PHOSPHATIDYL ETHANOLAMINE OR CARDIOLIPIN. SOME OF THE DETERGENTS LABELLED AS DMU DO NOT CONTAIN THE CARBON CHAIN, OR THE DISTAL GLUCOSE MOIETY. THE AUTHORS DO NOT KNOW FOR SURE THE IDENTITIES OF THE COMPLETE MOLECULES YET.
