ALPHA SUBUNIT OF A. BRASILENSE GLUTAMATE SYNTHASE

The structure was published by Binda, C., Bossi, R.T., Wakatsuki, S., et al., Curti, B., Vanoni, M.A., and Mattevi, A., in 2000 in a paper entitled "Cross-Talk and Ammonia Channeling between Active Centers in the Unexpected Domain Arrangement of Glutamate Synthase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.0 Å and deposited in 2000.

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