1g99 Summary



The structure was published by Buss, K.A., Cooper, D.R., Ingram-Smith, C., Ferry, J.G., Sanders, D.A., and Hasson, M.S., in 2001 in a paper entitled "Urkinase: structure of acetate kinase, a member of the ASKHA superfamily of phosphotransferases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2000.

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

This PDB entry contains multiple copies of the structure of ACETATE KINASE.

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