If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_02115
    • taxon = Archaea
    • fragment ≠ the sequence is fragmented

Special conditions

    • Subsequence at position 9 - 10 aligns to "[VTA]-F" in entry Q979C2 (individually applies "ATP")
    • Subsequence at position 14 - 17 aligns to "H-x-x-H" in entry Q979C2 (individually applies "ATP")
    • Subsequence at position 93 - 93 aligns to "[DN]" in entry Q979C2 (individually applies "ATP")
    • Subsequence at position 120 - 120 aligns to "[YHF]" in entry Q979C2 (individually applies "ATP; via amide nitrogen")

... then these annotations are applied i

Protein namei

  • Recommended name:
    FAD synthase (EC:2.7.7.2)
    Alternative name(s):
    Flavin adenine dinucleotide synthase
    FMN adenylyltransferase

Gene namei

  • Name:ribL

Pathwayi

  • Pathwayi: FAD biosynthesis

    This protein is involved in step 1 of the subpathway that synthesizes FAD from FMN. This subpathway is part of the pathway FAD biosynthesis, which is itself part of Cofactor biosynthesis.

Catalytic activityi

  • ATP + FMN = diphosphate + FAD.

Subunit structurei

  • Homodimer.

Sequence similaritiesi

Functioni

  • Catalyzes the transfer of the AMP portion of ATP to flavin mononucleotide (FMN) to produce flavin adenine dinucleotide (FAD) coenzyme.

Cofactori

Nucleotide bindingi

  • ATP (to residues corresponding to positions 9 - 10)
  • ATP (to residues corresponding to positions 14 - 17)

Binding sitei

  • ATP (to residues corresponding to position 93)
  • ATP; via amide nitrogen (to residues corresponding to position 120)
