CC -!- FUNCTION: N-malonyltransferase; part of the Fusarium detoxification of
CC benzoxazolinone cluster 2 (FDB2) involved in the degradation of
CC benzoxazolinones produced by the host plant (PubMed:19302487,
CC PubMed:26808652). Maize, wheat, and rye produce the 2 benzoxazinone
CC phytoanticipins 2,4-dihy-droxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA)
CC and 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) that, due to their
CC inherent instability once released, spontaneously degrade to the more
CC stable corresponding benzoxazolinones, 6-methoxy-2-benzoxazolinone
CC (MBOA) and 2-benzoxazolinone (BOA), respectively (PubMed:11876429). The
CC first step in the detoxification of benzoxazolinones involves the
CC hydrolysis of the cyclic ester bond of benzoxazolinones by the FDB1
CC cluster gamma-lactamase MBL1 to aminophenols (PubMed:26808652,
CC PubMed:12788712). MBL1 is able to convert BOA into 2-aminophenol (2-
CC AP), as well as MBOA into 5-methoxy-2-aminophenol (2-AMP)
CC (PubMed:26808652, PubMed:12788712). The FDB2 cluster N-
CC malonyltransferase FDB2/NAT1 then metabolizes aminophenols via N-
CC malonylation to non-toxic malonamic acids (PubMed:19302487,
CC PubMed:12788712). FDB2/NAT1 converts 2-AP into N-(2-hydroxyphenyl)
CC malonamic acid (HPMA) and 2-AMP into N-(2-hydroxy-4-methoxyphenyl)
CC malonamic acid (HMPMA) (PubMed:19302487, PubMed:12788712). The
CC duplicated dienlactone hydrolases DLH1 and DLH2 may provide redundant
CC function for hydrolyzing the lactone moiety in the BOA molecule
CC (Probable). The roles of the amidases an other enzymes encoded by the 2
CC FDB clusters have not been identified so far (Probable).
CC {ECO:0000269|PubMed:11876429, ECO:0000269|PubMed:12788712,
CC ECO:0000269|PubMed:19302487, ECO:0000269|PubMed:26808652,
CC ECO:0000305|PubMed:26808652}.
CC -!- PATHWAY: Xenobiotic degradation. {ECO:0000269|PubMed:19302487}.
CC -!- INDUCTION: Expression is induced in response to 2-benzoxasolinone (BOA)
CC exposure. {ECO:0000269|PubMed:19302487}.
CC -!- DISRUPTION PHENOTYPE: Eliminates the ability to metabolize BOA.
CC {ECO:0000269|PubMed:19302487}.
CC -!- MISCELLANEOUS: Fusarium verticillioides possesses 2 unlinked loci, FDB1
CC and FDB2, necessary for detoxification of antimicrobial compounds
CC produced by maize, including 2-benzoxazolinone (BOA) (Probable). The
CC FDB2 cluster arose as a duplication of the FDB1 cluster with
CC rearrangement and expansion by incorporating additional genes
CC (Probable). {ECO:0000305|PubMed:26808652}.
CC -!- SIMILARITY: Belongs to the arylamine N-acetyltransferase family.
CC {ECO:0000305}.
