X-RAY CRYSTALLOGRAPHIC INVESTIGATION OF SUBSTRATE BINDING TO CARBOXYPEPTIDASE A AT SUBZERO TEMPERATURE

The structure was published by Christianson, D.W. and Lipscomb, W.N., in 1986 in a paper entitled "X-ray crystallographic investigation of substrate binding to carboxypeptidase A at subzero temperature." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1982.

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

The PDB entry contains the structure of CARBOXYPEPTIDASE A. This molecule has the UniProt identifier P00730 (CBPA1_BOVIN)search. The sample contained 307 residues which is < 90% of the natural sequence. Out of 307 residues 307 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.
