WebThe peptidyl- prolyl isomerase cyclophilin A (CypA) binds a proline-rich loop on the surface of HIV-1 capsid (CA). This interaction increases HIV-1 infectivity in humans but promotes an anti-HIV-1 restriction activity in non-human primates. Efforts to understand these paradoxical effects of cyclophilin, along with more targeted approaches to ... WebAll organisms possess prolyl isomerase enzymes to catalyze this isomerization, and some bacteria have specialized prolyl isomerases associated with the ribosome. However, not all prolines are essential for folding, and protein folding may proceed at a normal rate despite having non-native conformers of many X–Pro peptide bonds. Uses [ edit]
