sulfate adenylyltransferase, small subunit; Metabolic assimilation of sulfur from inorganic sulfate, requires sulfate activation by coupling to a nucleoside, for the production of high-energy nucleoside phosphosulfates. This pathway appears to be similar in all prokaryotic organisms. Activation is first achieved through sulfation of sulfate with ATP by sulfate adenylyltransferase (ATP sulfurylase) to produce 5'-phosphosulfate (APS), coupled by GTP hydrolysis. Subsequently, APS is phosphorylated by an APS kinase to produce 3'-phosphoadenosine-5'-phosphosulfate (PAPS). In Escherichia coli, ATP sulfurylase is a heterodimer composed of two subunits encoded by cysD and cysN, with APS kinase encoded by cysC. These genes are located in a unidirectionally transcribed gene cluster, and have been shown to be required for the synthesis of sulfur-containing amino acids. Homologous to this E.coli activation pathway are nodPQH gene products found among members of the Rhizobiaceae family. These gene products have been shown to exhibit ATP sulfurase and APS kinase activity, yet are involved in Nod factor sulfation, and sulfation of other macromolecules.

Sulfate adenylyltransferase subunit 2; Sulfate adenylyltransferase subunits 1 and 2 form ATP sulfurylase (ATPS) that catalyzes the adenylation of sulfate producing adenosine 5'-phosphosulfate (APS) and diphosphate, the first enzymatic step in the sulfur assimilation pathway. APS synthesis involves the formation of a high-energy phosphoric-sulfuric acid anhydride bond driven by GTP hydrolysis by CysN, coupled to ATP hydrolysis by CysD. CysD belongs to the ATP pyrophosphatase (ATP PPase) family of proteins, members of which include PAPS reductase, GMP synthetase, asparagine synthetase, and NAD(+) synthetase. This subunit is responsible for directly forming APS under control of the G protein. A modified version of the P loop (PP-loop), the fingerprint peptide of mononucleotide-binding proteins, is present in the active site of the protein, which appears to be a positively charged cleft containing a number of conserved arginine and lysine residues.

uncharacterized phosphoadenosine phosphosulfate reductase-like proteins, similar to Escherichia coli YbdN; This subgroup contains Escherichia coli YbdN and other phosphoadenosine phosphosulfate (PAPS) reductase (or PAPS sulfotransferase EC 1.8.4.8)-like proteins. PAPS reductase is part of the adenine nucleotide alpha hydrolases superfamily also including N-type ATP PPases and ATP sulfurylases. A highly modified version of the P loop, the fingerprint peptide of mononucleotide-binding proteins, is present in the active site of the protein, which appears to be a positively charged cleft containing a number of conserved arginine and lysine residues. Although PAPS reductase has no ATPase activity, it shows a striking similarity to the structure of the ATP pyrophosphatase (ATP PPase) domain of GMP synthetase, indicating that both enzyme families have evolved from a common ancestral nucleotide-binding fold. The enzyme uses thioredoxin as an electron donor for the reduction of PAPS to phospho-adenosine-phosphate (PAP).

phosophoadenylyl-sulfate reductase (thioredoxin); This enzyme, involved in the assimilation of inorganic sulfate, is designated cysH in Bacteria and MET16 in Saccharomyces cerevisiae. Synonyms include phosphoadenosine phosphosulfate reductase, PAPS reductase, and PAPS reductase, thioredoxin-dependent. In a reaction requiring reduced thioredoxin and NADPH, it converts 3(prime)-phosphoadenylylsulfate (PAPS) to sulfite and adenosine 3(prime),5(prime) diphosphate (PAP). A related family of plant enzymes, scoring below the trusted cutoff, differs in having a thioredoxin-like C-terminal domain, not requiring thioredoxin, and in having a preference for 5(prime)-adenylylsulfate (APS) over PAPS.

Found in enterobacteria, cyanobacteria, and yeast, PAPS reductase is related to a group of plant (TIGR00424) and bacterial (TIGR02055) enzymes preferring 5'-adenylylsulfate (APS) over PAPS as a substrate for reduction to sulfite.

FAD synthase; FAD synthase (FMN:ATP adenylyl transferase (FMNAT); FAD pyrophosphorylase; Flavin adenine dinucleotide synthase (FADS); EC 2.7.7.2) is involved in the biochemical pathway for converting riboflavin into FAD. By sequence comparison, bacterial and eukaryotic FMNAT enzymes belong to two different protein superfamilies and apparently utilize different sets of active-site residues to accomplish the same chemistry. This subfamily includes eukaryotic FMNATs, which are members of the 3'-phosphoadenosine 5'-phosphosulfate (PAPS) reductase-like family belonging to the adenine nucleotide alpha hydrolase superfamily, which has conserved motifs different from those of nucleotidylyl transferases.
