3rg4 Summary


Crystal structure of the W5F mutant of human carbonic anhydrase II

The structure was published by Mikulski, R., Domsic, J.F., Ling, G., et al., Robbins, A.H., Silverman, D.N., and McKenna, R., in 2011 in a paper entitled "Structure and catalysis by carbonic anhydrase II: role of active-site tryptophan 5." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 Å and deposited in 2011.

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

The PDB entry contains the structure of Carbonic anhydrase 2. This molecule has the UniProt identifier P00918 (CAH2_HUMAN)search. The sample contained 260 residues which is 100% of the natural sequence. Out of 260 residues 257 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.
