CROSS-LINKED, CARBONMONOXY HEMOGLOBIN A

The structure was published by Schumacher, M.A., Dixon, M.M., Kluger, R., Jones, R.T., and Brennan, R.G., in 1995 in a paper entitled "Allosteric transition intermediates modelled by crosslinked haemoglobins." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1996.

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