From: The N-end rule and retroviral infection: no effect on integrase
Only some retroviral integrases bear a N-terminal type-2 destabilizing residue. A comparison of the identity and nature of the amino acid at the N-terminus of mature integrase for various retroviruses. Representatives of the family of retroviruses were chosen based on sequence characterization of the cleavage site or the integrase protein from the literature [22, 26–35].
