==THE MAJOR NAD(P)H:FMN OXIDOREDUCTASE FROM VIBRIO FISCHERI==

We have solved the crystal structure of FRase I, the major NAD(P)H:FMN, oxidoreductase of Vibrio fischeri, by the multiple isomorphous replacement, method (MIR) at 1.8 A resolution with the conventional R factor of 0.187., The crystal structure of FRase I complexed with its competitive inhibitor, dicoumarol, has also been solved at 2.2 A resolution with the conventional, R factor of 0.161. FRase I is a homodimer, having one FMN cofactor per, subunit, which is situated at the interface of two subunits. The overall, fold can be divided into two domains; 80% of the residues form a rigid, core and the remaining, a small flexible domain. The overall core folding, is similar to those of an NADPH-dependent flavin reductase of Vibrio, harveyi (FRP) and the NADH oxidase of Thermus thermophilus ...

[https://www.uniprot.org/uniprot/FRA1_ALIFS FRA1_ALIFS] Involved in bioluminescence. It is a good supplier of reduced flavin mononucleotide (FMNH2) to the bioluminescence reaction. Major FMN reductase. It is capable of using both NADH and NADPH as electron donors. As electron acceptor, FMN is the most effective, FAD is considerably effective, and riboflavin is the least effective.
