<p>Ac-Ser-Gln-Asn-Tyr-OH is an oligopeptide that is a substrate for enzymes that catalyze the hydrolysis of peptides. Ac-Ser-Gln-Asn-Tyr-OH has been shown to be an effective inhibitor of elastase and other proteases, with a kinetic mechanism involving a serine residue at position 1 as the nucleophile. This inhibitor binds to the active site of elastase and prevents access by the substrate. Acetylation at the C terminus may increase solubility, while substitution of tyrosine with a phenylalanine or tryptophan residue increases inhibitory activity. The optimum pH for this enzyme is around 7, while it’s inorganic nature makes it less sensitive to organic solvents.</p>
