PDB entry 3g15 (supersedes 3f2s)

Crystal structure of human choline kinase alpha in complex with hemicholinium-3 and ADP

The structure was published by Hong, B.S., Allali-Hassani, A., Tempel, W., et al., Dimov, S., Vedadi, M., and Park, H.W., in 2010 in a paper entitled "Crystal structures of human choline kinase isoforms in complex with hemicholinium-3: single amino acid near the active site influences inhibitor sensitivity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2009.

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

This PDB entry contains multiple copies of the structure of Choline kinase alpha.

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.
