Predict the fragments of the following peptide after cleavage by trypsin. GLMKTYPDSTA
A) GLM KTYPDSTA
B) GLMK TYPDSTA
C) GLMKTY PDSTA
D) GLMKTYPD STA

Question

Quizplus · Accepted Answer

Trypsin cleaves after arginine (R) and lysine (K) residues. In this peptide, trypsin will cleave after the lysine residue (K) between the amino acids GLMK and TYPDSTA, creating two fragments: GLMK and TYPDSTA. The correct choice is option B, which has the correct fragment, GLMK, and the remaining amino acids TYPDSTA.
