Inhibitors

Inhibitors Comment Organism Structure
additional information activity is inhibited by the interaction with serine acetyltransferase, the preceding enzyme in the metabolic pathway. Inhibition is exerted by the insertion of serine acetyltransferase C-terminal peptide into the enzyme's active site. The active site determinants that modulate the interaction specificity are investigated by comparing the binding affinity of thirteen pentapeptides, derived from the C-terminal sequences of serine acetyltransferase of closely related species. Subtle changes in protein active sites have profound effects on protein-peptide recognition. Affinity is strongly dependent on the pentapeptide sequence, signaling the relevance of P3-P4-P5 for the strength of binding, and P1-P2 mainly for specificity. The presence of an aromatic residue at P3 results in high affinity peptides with K(diss) in the micromolar and submicromolar range, regardless of the species. An acidic residue, like aspartate at P4, further strengthens the interaction Haemophilus influenzae
