1grv Summary



The structure was published by Guddat, L.W., Vos, S., Martin, J.L., Keough, D.T., and De Jersey, J., in 2002 in a paper entitled "Crystal Structures of Free, Imp-, and Gmp- Bound Escherichia Coli Hypoxanthine Phosphoribosyltransferase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2001.

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