Crystal structure of Q363F/R402A mutant flavocytochrome c3

The structure was published by Mowat, C.G., Pankhurst, K.L., Miles, C.S., et al., Walkinshaw, M.D., Reid, G.A., and Chapman, S.K., in 2002 in a paper entitled "Engineering Water to act as the active site acid catalyst in a soluble fumarate reductase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2002.

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