Two [Fe4S4] clusters have been identified and analyzed in bacterial and archaeal adenylylsulfate reductases. These enzymes are of importance in the sulfur cycle. The role of the iron-sulfur centres in relation to the third cofactor, FAD, has been studied. It was shown that the [Fe4S4] clusters function were electron transport guiding two electrons to the FAD catalytic site.234 A novel [Fe4S4] cluster with a high spin ground state (S = 3/2) was observed in the catalytic site of E. coli nitrate reductase A.235... [Pg.148]

In Fig. 4.2, the oxidation mechanisms of lactate with sulfate in the bacteria of Desulfovibrio genus is shown. In the reduction of sulfate, first the compound is changed into adenylylsulfate (APS) using ATP. APS is reduced by the catalysis of adenylylsulfate reductase to sulfite and AMP. The sulfite formed is reduced to... [Pg.55]

The sulfite oxidation pathway other than that mentioned above occurs in some thiobacilli sulfite reacts with AMP by the catalysis of adenylylsulfate reductase (APS reductase) to form APS and then APS reacts with diphosphate by the catalysis of sulfate adenylyltransferase to produce sulfate and ATP (Lyric and Suzuki, 1970c Stille and Triiper, 1984), or APS reacts with orthophosphate by the catalysis of sulfate adenylyltransferase (ADP) and ATP is formed from resulting ADP by the catalysis of adenylate kinase (Zimmermann et al., 1999). [Pg.68]

Adenylylsulfate reductase of T. thioparus with the molecular mass of 170 kDa has one molecule of FAD, 8-10 atoms of non-heme iron, and 4-5 atoms of inorganic sulfide in the molecule (Adachi and Suzuki, 1977). [Pg.68]

Adenylyisulfate reductases enzymes of sulfur metabolism which reduce either phosphoadenylylsul-fate (APS reductase) or adenylylsulfate. Adenylylsul-fate reductase (EC 1.8.99.2) is identical with one component of the sulfate reductase in sulfate assimilation, since adenylylsulfate is the donor of the sulfate group. Properties of some of these reductases are shown in the Table. In every case, the reductase is a complex of 3 components, an adenylylsulfate transferase (see Sulfate assimilation, Fig.1), a low-molecular-mass carrier, and the actual adenylylsulfate reductase. Phos-phoadenylylsulfate reductase from Saccharomyces cerevisiae requires NADPH, and has been partly purified. [Pg.17]
