HOW POTASSIUM AFFECTS THE ACTIVITY OF THE MOLECULAR CHAPERONE HSC70. II. POTASSIUM BINDS SPECIFICALLY IN THE ATPASE ACTIVE SITE

The structure was published by Wilbanks, S.M. and McKay, D.B., in 1995 in a paper entitled "How potassium affects the activity of the molecular chaperone Hsc70. II. Potassium binds specifically in the ATPase active site." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 1995.

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

The PDB entry contains the structure of 44K ATPASE FRAGMENT (N-TERMINAL) OF 7O kD HEAT-SHOCK COGNATE PROTEIN. This molecule has the UniProt identifier P19120 (HSP7C_BOVIN)search. The sample contained 386 residues which is < 90% of the natural sequence. Out of 386 residues 374 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.
