Alexander Varshavsky discovered, the half-lives of many cytoplasmic proteins vary with the identities of their N-terminal residues via the so-called N-end rule:-

A. Destabilizing N-terminal residues Asp, Arg, Leu, Lys, and Phe have half-lives of	i. Only 2 to 3 minutes,
B. Stabilizing N-terminal residues Ala, Gly, Met, Ser, Thr, and Val have half-lives of	ii. >10 hours in prokaryotes iii. >20 hours in eukaryotes.
