RN [2] RP PROTEIN SEQUENCE OF 2-16, AND CHARACTERIZATION. RX MEDLINE=20353466; PubMed=10894741; RX DOI=10.1128/JB.182.15.4304-4309.2000; RA Fonseca M.V., Escalante-Semerena J.C.; RT "Reduction of Cob(III)alamin to Cob(II)alamin in Salmonella enterica RT serovar typhimurium LT2."; RL J. Bacteriol. 182:4304-4309(2000). CC -!- FUNCTION: Catalyzes the reduction of soluble flavins by reduced CC pyridine nucleotides. Seems to reduces the complexed Fe(3+) iron CC of siderophores to Fe(2+), thus releasing it from the chelator (By CC similarity). CC -!- CATALYTIC ACTIVITY: FMNH(2) + NAD(P)(+) = FMN + NAD(P)H. CC -!- CATALYTIC ACTIVITY: 2 cob(II)alamin + NAD(+) = 2 CC aquacob(III)alamin + NADH. CC -!- SUBUNIT: Monomer (By similarity). CC -!- SIMILARITY: Belongs to the fre/luxG FAD/NAD(P) flavoprotein CC oxidoreductase family. CC -!- SIMILARITY: Contains 1 FAD-binding FR-type domain.
