CC   -!- FUNCTION: Sulfhydrylase; part of the gene cluster that mediates the
CC       biosynthesis of fusaric acid, a mycotoxin with low to moderate toxicity
CC       to animals and humans, but with high phytotoxic properties
CC       (PubMed:26662839). L-aspartate is suggested as fusaric acid amino acid
CC       precursor that is activated and further processed to O-acetyl-L-
CC       homoserine by cluster enzymes aspartate kinase FUB3 and homoserine O-
CC       acetyltransferase FUB5, as well as enzymes of the primary metabolism
CC       (PubMed:26662839). The polyketide synthase (PKS) FUB1 generates the
CC       triketide trans-2-hexenal which is presumptively released by the
CC       hydrolase FUB4 and linked to the NRPS-bound amino acid precursor by
CC       NAD(P)-dependent dehydrogenase FUB6 (PubMed:26662839). FUB1, FUB4, and
CC       the non-canonical NRPS Fub8 may form an enzyme complex
CC       (PubMed:26662839). Further processing of the NRPS-bound intermediate
CC       might be carried out by FUB6 and the O-acetylhomoserine FUB7, enabling
CC       a spontaneous electrocyclization to close the carbon backbone of
CC       fusaric acid (PubMed:26662839). Dihydrofusaric acid is likely to be
CC       released via reduction by the thioester reductase (TR) domain of FUB8
CC       whereupon the final oxidation to fusaric acid may (also) be performed
CC       by the FMN-dependent dehydrogenase FUB9 (PubMed:26662839).

CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250|UniProtKB:P50125};
CC   -!- PATHWAY: Mycotoxin biosynthesis. {ECO:0000269|PubMed:26662839}.
CC   -!- DISRUPTION PHENOTYPE: Impairs the production of fusaric acid, but leads
CC       to the accumulation of trans-2-hexenal (PubMed:26662839).
CC       {ECO:0000269|PubMed:26662839}.
CC   -!- BIOTECHNOLOGY: Fusaric acid is phytotoxic to plants such as cotton and
CC       banana (PubMed:20955724, PubMed:23922960). It has been shown to induce
CC       programmed cell death in plants (PubMed:16868776, PubMed:23838885). In
CC       addition to a mild toxicity to animals, fusaric acid exhibits
CC       acanthamoebicidal, antioomycete, and antimycobacterial activities
CC       (PubMed:17927749, PubMed:22864988, PubMed:21811925).
CC       {ECO:0000269|PubMed:16868776, ECO:0000269|PubMed:17927749,

CC       ECO:0000269|PubMed:23922960}.
CC   -!- SIMILARITY: Belongs to the trans-sulfuration enzymes family.
