Adenylyl sulfate

ATP interacts with APS to form PAPS, catalyzed by ATP adenylyl sulfate 3-phosphotransferase. [Pg.43]

This enzyme [EC 2.7.7.51] catalyzes reaction of adenylyl-sulfate and ammonia to form adenosine 5 -phosphorami-date and sulfate. [Pg.36]

Oxidation of sulfite to sulfate within cells occurs by a pathway through adenosine 5 -pHosphosulfate (APS, adenylyl sulfate). Oxidation via APS (Eq. 18-22) provides a means of substrate-level phosphorylation,... [Pg.1053]

In sulfation, substitution of polymeric chondroitin and chondroitin sulfates A and C by a hen-oviduct preparation has been described. The sulfate donor is adenylyl sulfate 3 -phosphate and a non-sulfated 2-acetamido-2-deoxy-D-galactosyl residue positioned internally in the polymer chain can be substituted.230 Evidence has been presented for another activity (from quail oviduct) that sulfates carbon atom 6 of a 2-acetamido-2-deoxy-D-galactosyl 4-C-sulfate group at the nonreducing end of the chain, giving the 4,6-di-C-sulfate.231... [Pg.203]

Adenylyl sulfate (APS) reductase is a flavoprotein, which contains iron and possibly acid-labile sulfide. It catalyzes the reduction of APS in the... [Pg.279]

Fig. 40. A proposed unified scheme of sulfate assimilation in algae. Adenylyl sulfate (APS) transfers the sulfo group via APS-sulfotransferase to form Car-S-SOr (Car = carrier), which is reduced further by thio-sulfonate reductase to Car-S-S which yields the thiol group of cysteine. In addition, if sulfite is released from Car-S-SOa (i.e., by thiol or from mutated sites) or if it enters the cell from outside, it can be reduced via a separate sulhte reductase. From Abrams and Schiff (57i). Fig. 40. A proposed unified scheme of sulfate assimilation in algae.

VIII Recent data of Bramlett and Peck (434) indicate that, as predicted in the above review, the adenylyl sulfate reductase of Desvlfovibrio vulgaris does contain acid-labile sulfide. The enzyme with a molecular weight of 220,000 has been shown to contain 1 mole of FAD, 12 g-atoms of iron and 12 moles of labile sulfide per mole. In addition, SDS-gel electrophoresis has revealed the presence of subunits with molecular weights of 20,000 and 72,000. [Pg.297]
