CRYSTAL STRUCTURE OF T4 POLYNUCLEOTIDE KINASE

The structure was published by Galburt, E.A., Pelletier, J., Wilson, G., and Stoddard, B.L., in 2002 in a paper entitled "Structure of a tRNA repair enzyme and molecular biology workhorse: T4 polynucleotide kinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.33 Å and deposited in 2002.

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

The PDB entry contains the structure of POLYNUCLEOTIDE KINASE. This molecule has the UniProt identifier P06855 (KIPN_BPT4)search. The sample contained 301 residues which is 100% of the natural sequence. Out of 301 residues 292 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 homotetramers.
