We report here two crystal structures of a recombinant single-chain Fv fragment of mAb 1696,expressed in E. coli, as a complex with a cross-reactive peptides from the HIV-1 PR and theHIV-2 PR at 2.7 ? resolution and 1.9 ? resolution respectively. On the basis of the interactionsseen in the complex three-dimensional structures, the cross-reactivity between mAb 1696 withthe HIV-1 and HIV-2 protease and their N-terminal peptides can be explained. In addition, acandidate mechanism of HIV PR inhibition by mAb 1696 is proposed which may help thedesign of alternative HIV protease inhibitors, aimed at dissociating the homodimeric viral enzyme."> We report here two crystal structures of a recombinant single-chain Fv fragment of mAb 1696,expressed in E. coli, as a complex with a cross-reactive peptides from the HIV-1 PR and theHIV-2 PR at 2.7 ? resolution and 1.9 ? resolution respectively.
