Heme inhibition of ferrisiderophore reductase in Bacillus subtilis.
نویسندگان
چکیده
Heme was a noncompetitive inhibitor (apparent K(i) and K'(i) = 0.043 mM) of a ferrisiderophore reductase purified from Bacillus subtilis; protoporphyrin IX had no effect. The cellular level of heme may partly regulate the function of this reductase to yield a controlled flow of iron into metabolism.

Ferrisiderophore reductase activity associated with an aromatic biosynthetic enzyme complex in Bacillus subtilis.
The cytoplasmic fractions obtained from Bacillus subtilis strains W168 and WB2802 catalyzed reductive release of iron from the ferric chelate of 2,3-dihydroxybenzoic acid (ferri-DHB), the ferrisiderophore produced by B. subtilis. Ferrisiderophore reductase activity may insert iron into metabolism. This activity required a reductant (reduced nicotinamide adenine dinucleotide phosphate was prefer...
متن کاملThe hemX gene of the Bacillus subtilis hemAXCDBL operon encodes a membrane protein, negatively affecting the steady-state cellular concentration of HemA (glutamyl-tRNA reductase).
The Bacillus subtilis hemAXCDBL operon encodes enzymes for the biosynthesis of uroporphyrinogen III from glutamyl-tRNA. The function of the hemX gene product was studied in this work. The deduced amino acid sequence suggests HemX to be an integral 32 kDa membrane protein. This was confirmed by experiments using Escherichia coli minicells and hemX-phoA gene fusions. Deletion of the hemX gene fro...
متن کاملThe crystal structure of the versatile cytochrome P450 enzyme CYP109B1 from Bacillus subtilis.
The crystal structure of the versatile CYP109B1 enzyme from Bacillus subtilis has been solved at 1.8 Å resolution. This is the first structure of an enzyme from this CYP family, whose members are prevalent across diverse species of bacteria. In the crystal structure the enzyme has an open conformation with an access channel leading from the heme to the surface. The substrate-free structure reve...
متن کاملHeme A synthase enzyme functions dissected by mutagenesis of Bacillus subtilis CtaA.
Heme A, as a prosthetic group, is found exclusively in respiratory oxidases of mitochondria and aerobic bacteria. Bacillus subtilis CtaA and other heme A synthases catalyze the conversion of a methyl side group on heme O into a formyl group. The catalytic mechanism of heme A synthase is not understood, and little is known about the composition and structure of the enzyme. In this work, we have:...
متن کاملAmmonification in Bacillus subtilis utilizing dissimilatory nitrite reductase is dependent on resDE.
During anaerobic nitrate respiration Bacillus subtilis reduces nitrate via nitrite to ammonia. No denitrification products were observed. B. subtilis wild-type cells and a nitrate reductase mutant grew anaerobically with nitrite as an electron acceptor. Oxygen-sensitive dissimilatory nitrite reductase activity was demonstrated in cell extracts prepared from both strains with benzyl viologen as ...
