1pbh Summary



The structure was published by Turk, D., Podobnik, M., Kuhelj, R., Dolinar, M., and Turk, V., in 1996 in a paper entitled "Crystal structures of human procathepsin B at 3.2 and 3.3 Angstroms resolution reveal an interaction motif between a papain-like cysteine protease and its propeptide." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.2 Å and deposited in 1997.

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

The PDB entry contains the structure of PROCATHEPSIN B. This molecule has the UniProt identifier P07858 (CATB_HUMAN)search. The sample contained 317 residues which is < 90% of the natural sequence. Out of 317 residues 316 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
