If the peptide Ser-Pro-Ser-Arg-Ala-Lys-Gly-Trp-Gly-Phe-Leu-Tyr-Val-Ser-Ala-Ala is fully digested by the protease pepsin, write down three possible products of the digestion. Use the three-letter (separated by dashes) or one-letter (no separators) amino acid abbreviations for your answers. If the peptide Ser-Pro-Ser-Arg-Ala-Lys-Gly-Trp-Gly-Phe-Leu-Tyr-Val-Ser-Ala-Ala is fully digested by the protease carboxypeptidase, write down three possible products of the digestion. Use the three-letter (separated by dashes) or one-letter (no separators) amino acid abbreviations for your answers.

Pepsin is an endopeptidase that cleaves peptide bonds, primarily at the carboxyl side of aromatic amino acids like phenylalanine (Phe, F), tryptophan (Trp, W), and tyrosine (Tyr, Y). Carboxypeptidase is an exopeptidase that cleaves peptide bonds at the carboxyl Show more…

The enzyme trypsin is a protease that splits peptide bonds on the carboxyl side of lysine or arginine. Treatment of a hexapeptide produces arg + ser-ala + leu-gly-lys. Which of the following are possible sequences of the amino acids in the hexapeptide? (There is at least one correct answer, maybe more.) arg-leu-gly-lys-ser-ala leu-gly-lys-arg-ser-ala ser-ala-leu-gly-lys-arg leu-gly-lys-ser-ala-arg ser-ala-arg-leu-gly-lys arg-ser-ala-leu-gly-lys
