THE DENSITY IS VERY LOW, BUT WE DO BELIEVE THE LIGAND IS PRESENT. WE THINK THAT THE LOW OCCUPANCY AND THE PARTIAL DISORDER OF UDP MOLECULE RESULTS IN VERY WEEK ELECTRON DENSITY. BOTH, THE ALPHA- AND BETA-PHOSPHATES OF UDP ARE DISORDERED, AND NO ELECTRON DENSITY IS VISIBLE FOR THEM. WE BELIEVE THE DISORDER OF PHOSPHATE GROUPS IS DUE TO THE ABSENCE OF DIVALENT CATION BOND TO THE STRUCTURE, WHICH USUALLY COORDINATES BETWEEN THE PHOSPHATE GROUPS AND THE ENZYME. COORDINATION OF THE DIVALENT CATION IS PH DEPENDENT, AT PH < 6 THE RESIDUE HIS258 IS FOUND PROTONATED, AND IS UNABLE TO COORDINATE DIVALENT CATIONS. WE BELIEVE THAT IS WHAT HAPPENS IN THIS CASE, RESULTING IN PARTIAL DISORDER OF UDP AND LOW OCCUPANCY. NONETHELESS, WEEK ELECTRON DENSITY IS FOUND FOR THE URIDINE MOIETY, SO WE FELL IT IS STILL INFORMATIVE TO INCLUDE IT IN THE STRUCTURE.
