The antibiotic biosynthesis monooxygenase (ABM) domain is found in proteins involved in a diverse range of biological processes, including metabolism, transcription, translation and biosynthesis of secondary metabolites:
- Streptomyces coelicolor ActVA-Orf6 monooxygenase, plays a role in the biosynthesis of aromatic polyketides, specifically the antibiotic actinorhodin, by oxidizing phenolic groups to quinones [1].
- Escherichia coli probable quinol monooxygenase YgiN, can oxidize menadiol to menadione [2].
- Staphylococcus aureus heme-degrading enzymes IsdG and IsdI [3,4].
- Staphylococci signal transduction protein TRAP (target of RNAIII- activating protein) [5].
- Mycobacterium tuberculosis heme-degrading monooxygenase MhuD (or Rv3592) [6].
- Mycobacterium tuberculosis putative monooxygenase Rv0793, might be involved in antibiotic biosynthesis, or may act as reactive oxygen species scavenger that could help in evading host defenses [7].
- Thermus thermophilus hypothetical protein TT1380 [8].
The ABM domain has only moderate sequence homology while sharing a high degree of structural similarity. The ABM domain crystallizes as a homodimer. Each monomer is composed of three α-helices (H1-3) and four β-strands (S1-4) and has a ferredoxin-like split βαβ-fold with an antiparallel β-sheet (see <1IUJ>). The β-sheets of two monomers form a 10-strand, anti-parallel β-barrel. The barrel is built of two smaller sheets that are connected by long C-terminal strands crossing over from one monomer to the other providing important interactions within the dimer. The core of the barrel is mainly hydrophobic [1,2,3,5,7,8].
The profile we developed covers the entire ABM domain.
