4k4q Summary


TL-3 inhibited Trp6Ala HIV Protease with 3-bromo-2,6-dimethoxybenzoic acid bound in flap site

The structure was published by Tiefenbrunn, T., Forli, S., Happer, M., et al., Elder, J.H., Olson, A.J., and Stout, C.D., in 2014 in a paper entitled "Crystallographic Fragment-Based Drug Discovery: Use of a Brominated Fragment Library Targeting HIV Protease." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2013.

The experimental data on which the structure is based was also 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.

The molecule most likely forms homodimers.
