2aim Summary



The structure was published by Gillmor, S.A., Craik, C.S., and Fletterick, R.J., in 1997 in a paper entitled "Structural determinants of specificity in the cysteine protease cruzain." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1997.

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

The PDB entry contains the structure of CRUZAIN. This molecule has the UniProt identifier P25779 (CYSP_TRYCR)search. The sample contained 215 residues which is < 90% of the natural sequence. Out of 215 residues 215 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.
