3b6r Summary


Crystal structure of Human Brain-type Creatine Kinase

The structure was published by Bong, S.M., Moon, J.H., Nam, K.H., Lee, K.S., Chi, Y.M., and Hwang, K.Y., in 2008 in a paper entitled "Structural studies of human brain-type creatine kinase complexed with the ADP-Mg2+-NO3- -creatine transition-state analogue complex" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2007.

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

This PDB entry contains multiple copies of the structure of Creatine kinase B-type.

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.
