| biotin synthase | The enzyme binds a [4Fe-4S] and a [2Fe-2S] cluster. In every reaction cycle, the enzyme consumes two molecules of AdoMet, each producing 5'-deoxyadenosine and a putative dethiobiotinyl carbon radical. Reaction with another equivalent of AdoMet results in abstraction of the C6 methylene pro-S hydrogen atom from 9-mercaptodethiobiotin, and the resulting carbon radical is quenched via formation of an intramolecular C-S bond, thus closing the biotin thiophane ring. The sulfur donor is believed to be the [2Fe-2S] cluster, which is sacrificed in the process, so that in vitro the reaction is a single turnover. In vivo, the [2Fe-2S] cluster can be reassembled by the Isc or Suf iron-sulfur cluster assembly systems, to allow further catalysis. Group: Enzymes. Synonyms: dethiobiotin:sulfur sulfurtransferase. Enzyme Commission Number: EC 2.8.1.6. CAS No. 80146-93-6. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

| Ds(+)-threo-Isocitric acid trisodium salt | Anticoagulant that retains platelets functionality. Buffers Ca2+ activity in physiological range (~1mM). Bypasses the metabolic blockade, may permit heme biosynthesis but does not suffice to reverse the iron-restriction response. Stabilizes the iron-sulfur cluster and is predicted to restore aconitase to its 'high iron' conformation and thereby dissociates the PKC-associated signaling complexes whose hyperactivation impairs Epo responsiveness. Binds IDH (isocitrate dehydrogenase), an excellent candidate for participating, along with aconitase and PKC, in an iron restriction signalosome. Contributes to heme biosynthesis which may account for its greater potency in restoring erythroid differentiation. Group: Biochemicals. Alternative Names: (1R,2S)-1-Hydroxy-1,2,3-propanetricarboxylic acid; (2R,3S)-Isocitric acid trisodium salt. Grades: Highly Purified. CAS No. 903507-52-8. Pack Sizes: 25mg, 100mg.

| NiFe-type cytoplasmic hydrogenase from Pyrococcus furiosus, recombinant | The [NiFe] hydrogenases contain a minimum of two subunits known as the small (S) and large (L) subunits. The small subunit contains three iron-sulfur clusters while the large subunit contains the active site, a nickel-iron center which is connected to the solvent by a molecular tunnel. To date, periplasmic, cytoplasmic, and membrane-bound hydrogenases have been found. [NiFe] hydrogenases are known to be deactivated by molecular oxygen (O2). The [NiFe] hydrogenase of Pyrococcus furiosus is heterotetrameric wherein the additional two subunits allow the enzyme to use NAD(P)(H) as an electron carrier. Group: Enzymes.

| pheophorbide a oxygenase | This enzyme catalyses a key reaction in chlorophyll degradation, which occurs during leaf senescence and fruit ripening in higher plants. The enzyme from Arabidopsis contains a Rieske-type iron-sulfur cluster and requires reduced ferredoxin, which is generated either by NADPH through the pentose-phosphate pathway or by the action of photosystem I. While still attached to this enzyme, the product is rapidly converted into primary fluorescent chlorophyll catabolite by the action of EC 1.3.7.12, red chlorophyll catabolite reductase. Pheophorbide b acts as an inhibitor. In 18O2 labelling experiments, only the aldehyde oxygen is labelled, suggesting that the other oxygen atom may originate from H2O. Group: Enzymes. Synonyms: pheide a monooxygenase; pheide a oxygenase; PaO; PAO. Enzyme Commission Number: EC 1.14.15.17. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C.

| quinolinate synthase | An iron-sulfur protein that requires a [4Fe-4S] cluster for activity. Quinolinate synthase catalyses the second step in the de novo biosynthesis of NAD+ from aspartate in some bacteria, with EC 1.4.3.16 (L-aspartate oxidase) catalysing the first step and EC 2.4.2.19 [nicotinate-nucleotide diphosphorylase (carboxylating)] the third step. In Escherichia coli, two of the residues that are involved in the [4Fe-4S] cluster binding appear to undergo reversible disulfide-bond formation that regulates the activity of the enzyme. Group: Enzymes. Synonyms: NadA; QS; quinolinate synthetase. Enzyme Commission Number: EC 2.5.1.72. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C.

| tetrachloroethene reductive dehalogenase | This enzyme allows the common pollutant tetrachloroethene to support bacterial growth and is responsible for disposal of a number of chlorinated hydrocarbons by this organism. The reaction occurs in the reverse direction. The enzyme also reduces trichloroethene to dichloroethene. Although the physiological reductant is unknown, the supply of reductant in some organisms is via reduced menaquinone, itself formed from molecular hydrogen, via EC 1.12.5.1 (hydrogen:quinone oxidoreductase). The enzyme contains a corrinoid and two iron-sulfur clusters. Methyl viologen can act as electron donor. Group: Enzymes. Synonyms: tetrachloroethene reductase. Enzyme Commission Number: EC 1.97.1.8.

| threonine ammonia-lyase | Most enzymes that catalyse this reaction are pyridoxal-phosphate-dependent, although some enzymes contain an iron-sulfur cluster instead. The reaction catalysed by both types of enzymes involves the initial elimination of water to form an enamine intermediate (hence the enzyme's original classification as EC 4.2.1.16, threonine dehydratase), followed by tautomerization to an imine form and hydrolysis of the C-N bond. The latter reaction, which can occur spontaneously, is also be catalysed by EC 3.5.99.10, 2-iminobutanoate/2-iminopropanoate deaminase. The enzymes from a number of sources also act on L-serine, cf. EC 4.3.1.17, L-serine ammonia-lyase. Group: Enzymes. Synonyms: threonine deaminase; L-serine dehydratase; serine deaminase; L-threonine dehydratase; threonine dehydrase; L-threonine deaminase; threonine dehydratase; L-threonine hydro-lyase (deaminating); L-threonine.
