1hkc Summary



The structure was published by Aleshin, A.E., Zeng, C., Bartunik, H.D., Fromm, H.J., and Honzatko, R.B., in 1998 in a paper entitled "Regulation of hexokinase I: crystal structure of recombinant human brain hexokinase complexed with glucose and phosphate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1998.

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

The PDB entry contains the structure of D-GLUCOSE 6-PHOSPHOTRANSFERASE. This molecule has the UniProt identifier P19367 (HXK1_HUMAN)search. The sample contained 917 residues which is 100% of the natural sequence. Out of 917 residues 899 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 most likely forms homodimers.
