1cc1 Summary



The structure was published by Garcin, E., Vernede, X., Hatchikian, E.C., Volbeda, A., Frey, M., and Fontecilla-Camps, J.C., in 1999 in a paper entitled "The crystal structure of a reduced [NiFeSe] hydrogenase provides an image of the activated catalytic center" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.15 Å and deposited in 1999.

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

This PDB entry contains a complex of 2 biomacromolecules, namely HYDROGENASE (SMALL SUBUNIT) and HYDROGENASE (LARGE SUBUNIT).
