1hcb Summary



The structure was published by Kumar, V. and Kannan, K.K., in 1994 in a paper entitled "Enzyme-substrate interactions. Structure of human carbonic anhydrase I complexed with bicarbonate." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.6 Å and deposited in 1994.

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

The PDB entry contains the structure of CARBONIC ANHYDRASE I. This molecule has the UniProt identifier P00915 (CAH1_HUMAN)search. The sample contained 260 residues which is 100% of the natural sequence. Out of 260 residues 258 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.
