Crystal structure of a complex of mutant HIV-1 protease (A71V, V82T, I84V) with a hydroxyethylamine peptidomimetic inhibitor
OverviewOverview
Two new X-ray structures of an HIV-1 protease mutant (A71V, V82T, I84V) in complex with inhibitors SE and SQ, pseudotetrapeptide inhibitors with an acyclic S-hydroxyethylamine isostere, were determined. Comparison of eight structures exploring the binding of four similar inhibitors--SE, SQ (S-hydroxyethylamine isostere), OE (ethyleneamine), and QF34 (hydroxyethylene)--to wild-type and A71V/V82T/I84V HIV-1 protease elucidates the principles of altered interaction with changing conditions. The A71V mutation, which is distant from the active site, causes changes in the structure of the enzyme detectable by the means of X-ray structure analysis, and a route of propagation of the effect toward the active site is proposed.
