EACH MONOMER OF GME K178R CONTAINS A MIXTURE OF COMPOUNDS IN THE ACTIVE SITE -NAD AND NADH IN THE NUCLEOTIDE BINDING SITE, GDP-BETA-L-GULOSE AND GDP-BETA-L-4- KETO-GULOSE IN THE NUCLEOTIDE SUGAR BINDING SITE. DURING REFINEMENT THE CONSTANT PORTION OF EACH MOLECULE (ADP FOR NAD, GMP FOR THE GDP-SUGARS, AS THE SECOND PHOSPHATE GROUP MOVES WITH DIFFERENT LIGANDS) WAS FIXED WITH OCCUPANCY OF 1 AND LINKED TO TWO VARIABLE PORTIONS WITH PARTIAL OCCUPANCY.
