Crystal structure of human carbonic anhydrase isozyme XIII with the inhibitor.

The structure was published by Dudutiene, V., Zubriene, A., Smirnov, A., et al., Manakova, E., Grazulis, S., and Matulis, D., in 2013 in a paper entitled "4-Substituted-2,3,5,6-tetrafluorobenzenesulfonamides as inhibitors of carbonic anhydrases I, II, VII, XII, and XIII." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 2012.

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

This PDB entry contains multiple copies of the structure of Carbonic anhydrase 13.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
