1qbr Summary



The structure was published by Jadhav, P.K., Ala, P., Woerner, F.J., et al., Garber, S.S., Anton, E.D., and Bacheler, L.T., in 1997 in a paper entitled "Cyclic urea amides: HIV-1 protease inhibitors with low nanomolar potency against both wild type and protease inhibitor resistant mutants of HIV." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

This PDB entry contains multiple copies of the structure of HIV-1 PROTEASE.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
