| 3-hexulose-6-phosphate synthase | Requires Mg2+ or Mn2+ for maximal activity. The enzyme is specific for D-ribulose 5-phosphate as substrate as ribose 5-phosphate, xylulose 5-phosphate, allulose 6-phosphate and fructose 6-phosphate cannot act as substrate. In addition to formaldehyde, the enzyme can also use glycolaldehyde and methylglyoxal. This enzyme, along with EC 5.3.1.27, 6-phospho-3-hexuloisomerase, plays a key role in the ribulose-monophosphate cycle of formaldehyde fixation, which is present in many microorganisms that are capable of utilizing C1-compounds. The hyperthermophilic and anaerobic archaeon Pyrococcus horikoshii OT3 constitutively produces a bifunctional enzyme that sequentially catalyses the reactions of this enzyme and EC 5.3.1.27, 6-phospho-3-hexuloisomerase. This enzyme is a member of the orotidine 5'-monophosphate decarboxylase (OMPDC) suprafamily. Group: Enzymes. Synonyms: D-arabino-3-hexulose 6-phosphate formaldehyde-lyase; 3-hexulosephosphate synthase; 3-hexulose phosphate synthase; HPS. Enzyme Commission Number: EC 4.1.2.43.

| α,α-trehalose synthase | Requires Mg2+ for maximal activity. The enzyme-catalysed reaction is reversible. In the reverse direction to that shown above, the enzyme is specific for α,α-trehalose as substrate, as it cannot use α- or β-paranitrophenyl glucosides, maltose, sucrose, lactose or cellobiose. While the enzymes from the thermophilic bacterium Rubrobacter xylanophilus and the hyperthermophilic archaeon Pyrococcus horikoshii can use ADP-, UDP- and GDP-α-D-glucose to the same extent, that from the hyperthermophilic archaeon Thermococcus litoralis has a marked preference for ADP-α-D-glucose and that from the hyperthermophilic archaeon Thermoproteus tenax has a marked preference for UDP-α-D-glucose. Group: Enzymes. Synonyms: trehalose synthase; trehalose synthetase; UDP-glucose:glucose 1-glucosyltransferase; TreT; PhGT; ADP-glucose:D-glucose 1-α-D-glucosyltransferase.

| mannosyl-3-phosphoglycerate synthase | Requires Mg2+. The enzyme is absolutely specific for GDPmannose and 3-phosphoglycerate, and transfers the mannosyl group with retention of configuration. In the hyperthermophilic archaeon Pyrococcus horikoshii, the mannosyl-3-phosphoglycerate formed is subsequently dephosphorylated by a specific phosphatase, EC 3.1.3.70 (mannosyl-3-phosphoglycerate phosphatase), producing mannosylglycerate. Group: Enzymes. Synonyms: MPG synthase; GDP-mannose:3-phosphoglycerate 3-α-D-mannosyltransferase. Enzyme Commission Number: EC 2.4.1.217. CAS No. 393512-63-5.

| sulfhydrogenase | An iron-sulfur protein. The enzyme from the hyperthermophilic archaeon Pyrococcus furiosus is part of two heterotetrameric complexes where the β and γ subunits function as sulfur reductase and the α and Δ subunits function as hydrogenases (EC 1.12.1.3, hydrogen dehydrogenase [NADP+] and EC 1.12.1.4, hydrogen dehydrogenase [NAD(P)+], respectively). Sulfur can also be used as substrate, but since it is insoluble in aqueous solution and polysulfide is generated abiotically by the reaction of hydrogen sulfide and sulfur, polysulfide is believed to be the true substrate. Group: Enzymes. Synonyms: sulfur reductase. Enzyme Commission Number: EC 1.12.98.4. 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. EXWM-0527; sulfhydrogenase; EC 1.12.98.4; sulfur reductase. Cat No: EXWM-0527. | |
