The flavoprotein moiety of Escherichia coli sulfite reductase (SiR-FP) is homologous to electron transfer proteins such as cytochrome-P450 reductase (CPR) or nitric oxide synthase (NOS). We report on the three-dimensional structure of SiR-FP18, the flavodoxin-like domain of SiR-FP, which has been determined by NMR. In the holoenzyme, this domain plays an important role by shuttling electrons from the FAD to the hemoprotein (the beta-subunit). The structure presented here was determined using distance and torsion angle information in combination with residual dipolar couplings determined in two different alignment media. Several protein-FMN NOEs allowed us to place the prosthetic group in its binding pocket. The structure is well-resolved, and (15)N relaxation data indicate that SiR-FP18 is a compact domain. The binding interface with cytochrome c, a nonphysiological electron acceptor, has been determined using chemical shift mapping. Comparison of the SiR-FP18 structure with the corresponding domains from CPR and NOS shows that the fold of the protein core is highly conserved, but the analysis of the electrostatic surfaces reveals significant differences between the three domains. These observations are placed in the physiological context so they can contribute to the understanding of the electron transfer mechanism in the SiR holoenzyme.
