CC   -!- FUNCTION: Esterase; 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   -!- INDUCTION: Expression is induced in response to 2-benzoxasolinone (BOA)
CC       exposure. {ECO:0000269|PubMed:26808652}.
CC   -!- DISRUPTION PHENOTYPE: Does not affect tolerance to 2-benzoxazolinone
CC       (BOA). {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 AB hydrolase 3 family. {ECO:0000305}.
