1ofd Summary



The structure was published by Van Den Heuvel, R.H.H., Svergun, D.I., Petoukhov, M.V., et al., Ravasio, S., Vanoni, M.A., and Mattevi, A., in 2003 in a paper entitled "The Active Conformation of Glutamate Synthase and its Binding to Ferredoxin" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2003.

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