3znc Summary



The structure was published by Stams, T., Chen, Y., Boriack-Sjodin, P.A., et al., Laipis, P., Silverman, D.N., and Christianson, D.W., in 1998 in a paper entitled "Structures of murine carbonic anhydrase IV and human carbonic anhydrase II complexed with brinzolamide: molecular basis of isozyme-drug discrimination." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 1998.

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

The PDB entry contains the structure of CARBONIC ANHYDRASE IV. This molecule has the UniProt identifier Q64444 (CAH4_MOUSE)search. The sample contained 258 residues which is 90% of the natural sequence. Out of 258 residues 249 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 most likely forms homodimers.
