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

Catalytic activityi

  • ATP + FMN = diphosphate + FAD.

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.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes FAD from FMN, the pathway FAD biosynthesis and in Cofactor biosynthesis.

Functioni

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

Subunit structurei

  • Homodimer.

Sequence similaritiesi

Cofactori

Binding sitei
