Crystal structure of Pseudomonas 7A Glutaminase-asparaginase with the inhibitor donv covalently bound in the active site

The structure was published by Ortlund, E., Lacount, M.W., Lewinski, K., and Lebioda, L., in 2000 in a paper entitled "Reactions of Pseudomonas 7A glutaminase-asparaginase with diazo analogues of glutamine and asparagine result in unexpected covalent inhibitions and suggests an unusual catalytic triad Thr-Tyr-Glu." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1999.

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

This PDB entry contains multiple copies of the structure of GLUTAMINASE-ASPARAGINASE.

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 homotetramers.
