Heteronuclear NMR methods have been used to elucidate the secondary structure and the general tertiary fold of the protein NodF from Rhizobium leguminosarum. A similarity to acyl carrier proteins of the fatty acid synthase system had been suggested by the presence of a phosphopantetheine prosthetic group and a short stretch of sequence homology near the prosthetic group attachment site. NMR results suggest that the structural homology extends well beyond this region. Both proteins have three well-formed helices which fold in a parallel-antiparallel fashion and a prosthetic group attachment site near the beginning of the second helix.
