CARICA PAPAYA CHYMOPAPAIN AT 1.7 ANGSTROMS RESOLUTION

The structure was published by Maes, D., Bouckaert, J., Poortmans, F., Wyns, L., and Looze, Y., in 1996 in a paper entitled "Structure of chymopapain at 1.7 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 1996.

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

The PDB entry contains the structure of CHYMOPAPAIN. This molecule has the UniProt identifier P14080 (PAPA2_CARPA)search. The sample contained 218 residues which is < 90% of the natural sequence. Out of 218 residues 218 were observed and are deposited in the PDB.

The molecule most likely forms homodimers.
