Crystal structure of a complex of mutant HIV-1 protease (A71V, V82T, I84V) with a hydroxyethylamine peptidomimetic inhibitor BOC-PHE-PSI[S-CH(OH)CH2NH]-PHE-GLU-PHE-NH2
Overview
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.
