Crystallographic data were collected at the EMBL-beamline BW7B at DESY in Hamburg, Germany. We thank the beamline scientists for their assistance, and Ingrid Dreveny, Gunter Gartler, Gerwald Jogl, and Oliver Sauer for their help during data collection. This research emerged from a collaboration with Prof. W. Buckel (Marburg) who supplied us with clones of the glutamate mutase proteins. , Gruber K, Reitzer R, Kratky C, Angew Chem Int Ed Engl. 2001 Sep 17;40(18):3377-3380. PMID:11592143
