1o6y Summary



The structure was published by Ortiz-Lombardia, M., Pompeo, F., Boitel, B., and Alzari, P.M., in 2003 in a paper entitled "Crystal Structure of the Catalytic Domain of the Pknb Serine/Threonine Kinase from Mycobacterium Tuberculosis" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2002.

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

The PDB entry contains the structure of SERINE/THREONINE-PROTEIN KINASE PKNB. This molecule has the UniProt identifier P9WI81 (PKNB_MYCTU)search. The sample contained 299 residues which is < 90% of the natural sequence. Out of 299 residues 254 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.
