5.4.2.2	phosphoprotein	phosphorylation of active site Ser108 in wild-type and mutant enzymes	
5.4.2.2	phosphoprotein	phosphorylation of conserved catalytic active site residue Ser108 has broad effects on residues in multiple domains. Dephosphorylation of the enzyme may play two critical functional roles: a direct role in the chemical step of phosphoryl transfer and secondly through propagation of structural flexibility. Dephosphorylation has minimal effects on crystal structure of the enzyme
