analysis of interaction energies among the active site residues His254, Ser201, and Asn154, which form a hydrogen bonding network. In mild detergent, the active site residues are weakly coupled with interaction energies of ?1.4 kcal/mol between His254 and Ser201 and ?0.2 kcal/mol between Ser201 and Asn154. These residues are important for function and also for the folding cooperativity of GlpG. The weak interaction between Ser and His in the catalytic dyad may partly explain the unusually slow proteolysis by GlpG | Escherichia coli |
