3e31 Summary


H. influenzae beta-carbonic anhydrase, variant V47A

The structure was published by Rowlett, R.S., Hoffmann, K.M., Failing, H., Mysliwiec, M.M., and Samardzic, D., in 2010 in a paper entitled "Evidence for a bicarbonate "escort" site in Haemophilus influenzae beta-carbonic anhydrase ." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.95 Å and deposited in 2008.

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