1fsq Summary



The structure was published by Cox, J.D., Hunt, J.A., Compher, K.M., Fierke, C.A., and Christianson, D.W., in 2000 in a paper entitled "Structural influence of hydrophobic core residues on metal binding and specificity in carbonic anhydrase II." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2000.

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