Adenine nucleotide alpha hydrolase (AANH) superfamily; The adenine nucleotide alpha hydrolase (AANH) superfamily includes N-type ATP PPases, ATP sulfurylases, universal stress response proteins (USPs), and electron transfer flavoproteins (ETFs). The domain forms an alpha/beta/alpha fold which binds to adenosine nucleotide.

putative sulfurtransferase DndC; Members of this protein family are the DndC protein from the dnd (degradation during electrophoresis) operon. The dnd phenotype reflects a sulfur-containing modification to DNA. This operon is sparsely and sporadically distributed among bactera; among the first eight examples are members from the Actinobacteria, Firmicutes, Gammaproteobacteria, Cyanobacteria. DndC is suggested to be a sulfurtransferase. [DNA metabolism, Restriction/modification]

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.
