MFS-type transporter; part of the Fusarium detoxification of benzoxazolinone cluster 2 (FDB2) involved in the degradation of benzoxazolinones produced by the host plant (PubMed:26808652). Maize, wheat, and rye produce the 2 benzoxazinone phytoanticipins 2,4-dihy-droxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) and 2,4-dihydroxy-1,4-benzoxazin-3-one (DIBOA) that, due to their inherent instability once released, spontaneously degrade to the more stable corresponding benzoxazolinones, 6-methoxy-2-benzoxazolinone (MBOA) and 2-benzoxazolinone (BOA), respectively (PubMed:11876429). Fusarium verticillioides possesses 2 unlinked loci, FDB1 and FDB2, necessary for detoxification of antimicrobial compounds produced by maize, including 2-benzoxazolinone (BOA) (Probable). The FDB2 cluster arose as a duplication of the FDB1 cluster with rearrangement and expansion by incorporating additional genes (Probable). Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.
