Crystal Structure of Human Carbonic Anhydrase VII [isoform 1], CA7

The structure was published by Ugochukwu, E., Shafqat, N., Pilka, E., et al., Carpenter, E.P., Yue, W.W., and Oppermann, U., in in a paper entitled "Crystal Structure of Human Carbonic Anhydrase VII [isoform 1], CA7" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.32 Å and deposited in 2010.

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

The PDB entry contains the structure of Carbonic anhydrase 7. This molecule has the UniProt identifier P43166 (CAH7_HUMAN)search. The sample contained 281 residues which is 98% of the natural sequence. Out of 281 residues 251 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.
