1bg0 Summary



The structure was published by Zhou, G., Somasundaram, T., Blanc, E., Parthasarathy, G., Ellington, W.R., and Chapman, M.S., in 1998 in a paper entitled "Transition state structure of arginine kinase: implications for catalysis of bimolecular reactions." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.86 Å and deposited in 1998.

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

The PDB entry contains the structure of ARGININE KINASE. This molecule has the UniProt identifier P51541 (KARG_LIMPO)search. The sample contained 356 residues which is 100% of the natural sequence. Out of 356 residues 356 were observed and are deposited in the PDB.

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 is most likely monomeric.
