    The protein

    Catalyzed reaction/ biological activity

  • ATP sulfate = diphosphate adenylyl sulfate (according to Swiss-Prot)

    • Protein family

  • sulfate adenylyltransferase family (according to Swiss-Prot)

    • Paralogous protein(s)

  • [protein|search|YitA]

    • Structure

  • [PDB|1V47] (from ''Thermus thermophilus'', 42% identity) [Pubmed|15065853]

    • Expression and Regulation

    Operon

  • ''[protein|search|cysH]-[protein|search|cysP]-[protein|search|sat]-[protein|search|cysC]-[protein|search|ylnD]-[protein|search|ylnE]-[protein|search|ylnF]'' [Pubmed|11004190]

    • [SW|Sigma factor]

  • [protein|search|SigA] [Pubmed|11004190]

    • Regulation
