Crystal Structure of Yeast Hexokinase PII with the correct amino acid sequence

The structure was published by Kuser, P.R., Krauchenco, S., Antunes, O.A., and Polikarpov, I., in 2000 in a paper entitled "The high resolution crystal structure of yeast hexokinase PII with the correct primary sequence provides new insights into its mechanism of action." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2001.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of hexokinase PII. This molecule has the UniProt identifier P04807 (HXKB_YEAST)search. The sample contained 486 residues which is 100% of the natural sequence. Out of 486 residues 469 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.
