Post-translational processing

Question 1

folding

Answer 1

2,3,4 prime folding

Question 2

addition

Answer 2

ligation of other biomolecules onto a peptide.

ex: phosphorylation (activating or deactivating), carboxylation (create Ca binding site), glycosylation (determine expoort destination), prenylation (add lipids to membrane-bound enzymes)

Question 3

cleavage

Answer 3

hydrolysis of large peptide into smaller pieces can reveal biologically acitve proteins within the peptide.
