dbaB

Gene
dbaB
Protein
FAD-dependent monooxygenase dbaB
Organism
Emericella nidulans (strain FGSC A4 / ATCC 38163 / CBS 112.46 / NRRL 194 / M139)
Length
393 amino acids
Function
FAD-dependent monooxygenase; part of the gene cluster that mediates the biosynthesis of the antibiotic 2,4-dihydroxy-3-methyl-6-(2-oxopropyl)benzaldehyde (DHMBA) and its derivatives (PubMed:22510154, PubMed:23001671). The direct non-reducing polyketide synthase dbaI product is 2,4-dihydroxy-3-methyl-6-(2-oxopropyl)benzaldehyde (DHMBA), produced by condensation of one acetyl-CoA starter unit with 4 malonyl-CoA units and one methylation step (PubMed:22510154). The FAD-dependent monooxygenase dbaH is responsible for the synthesis of yellow pigments derived from the oxidation of DHMBA (PubMed:23001671). The roles of dbaB, C, E and F have still to be determined (Probable).
Similarity
Belongs to the paxM FAD-dependent monooxygenase family.
