Crystal structures of inactive variants of HIV-1 protease bound to peptides have revealed how the enzyme recognizes its endogenous substrates. The best of the known substrates is, however, a nonnatural substrate that was identified by directed evolution. The crystal structure of the complex between this substrate and the D25N variant of the protease is reported at a resolution of 1.1 Å. The structure has several unprecedented features, especially the formation of additional hydrogen bonds between the enzyme and the substrate. This work expands the understanding of molecular recognition by HIV-1 protease and informs the design of new substrates and inhibitors.

Abstract Ectocarpene, (+)-(6S)-(1Z-butenyl)-2,5-cycloheptadiene, is the mating pherom one of the three distantly related seaweeds Ectocarpus siliculosus, Sphacelaria rigidula and Adenocystis utricularis. Analogu es of this pheromone, dif­fering in position and π-electron density of the double bond in the C4-side chain, were synthesized and assayed for biological activity. The results suggest, that the fundamen­tal molecular recognition process is conservative in all species, while receptor dynamics and -topologies have been modified by individual developments and expressions dur­ing plant phylogeny.
