THE CRYSTAL STRUCTURE OF A CYS25ALA MUTANT OF HUMAN PROCATHEPSIN S

The structure was published by Kaulmann, G., Palm, G.J., Schilling, K., Hilgenfeld, R., and Wiederanders, B., in 2006 in a paper entitled "The Crystal Structure of a Cys25 -> Ala Mutant of Human Procathepsin S Elucidates Enzyme-Prosequence Interactions." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2005.

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

The PDB entry contains the structure of PROCATHEPSIN S. This molecule has the UniProt identifier P25774 (CATS_HUMAN)search. The sample contained 315 residues which is 100% of the natural sequence. Out of 315 residues 308 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
