Chemical modification with 2,3-butanedione in borate buffer indicates that nine of ten glycolytic enzymes studied contain arginyl residues at their active sites. Fructose-1,6-diphosphatase also has arginines at its binding site for the allosteric inhibitor, adenosine monophosphate. These and other data suggest that, as a general rule, enzymes acting on anionic substrates or cofactors will probably contain arginyl residues as components of their ligand binding sites. This could account in part… CONTINUE READING
