The half-lives of many cytoplasmic proteins vary with the identities of their N-terminal residues via the  N-end rule.

a) Proteins with the “destabilizing” N-terminal residues contain Asp, Arg, Leu, Lys, and Phe with their half-lives > 2 to 3 hours

b) Proteins with the “destabilizing” N-terminal residues with their half-lives of only 2 to 3 minutes contain; Asp, Arg, Leu, Lys, and Phe

c) Proteins contain Ala, Gly, Met, Ser, Thr, and Val have half-lives of >10 hours are stabilizing N-terminal residue in prokaryotes

d) Those with the “stabilizing” N-terminal residues Ala, Gly, Met, Ser, Thr, and Val have half-lives of >20 hours in eukaryotes
