CC -!- FUNCTION: Probable aminotransferase; part of the gene cluster that
CC mediates the biosynthesis of gliotoxin, a member of the
CC epipolythiodioxopiperazine (ETP) class of toxins characterized by a
CC disulfide bridged cyclic dipeptide (PubMed:15979823, PubMed:21612254).
CC The first step in gliotoxin biosynthesis is the condensation of serine
CC and phenylalanine to form the cyclo-L-phenylalanyl-L-serine
CC diketopiperazine (DKP) by the NRPS gliP (PubMed:17154540,
CC PubMed:21612254). GliP is also able to produce the DKP cyclo-L-
CC tryptophanyl-L-serine, suggesting that the substrate specificity of the
CC first adenylation (A) domain in gliP is sufficiently relaxed to
CC accommodate both L-Phe and L-Trp (PubMed:23434416). The cytochrome P450
CC monooxygenase gliC has been shown to catalyze the subsequent
CC hydroxylation of the alpha-carbon of L-Phe in cyclo-L-phenylalanyl-L-
CC serine whereas the second cytochrome P450 enzyme, gliF, is presumably
CC involved in the modification of the DKP side chain (PubMed:24039048,
CC PubMed:23434416). The glutathione S-transferase (GST) gliG then forms a
CC bis-glutathionylated biosynthetic intermediate which is responsible for
CC the sulfurization of gliotoxin (PubMed:21513890, PubMed:21749092). This
CC bis-glutathionylated intermediate is subsequently processed by the
CC gamma-glutamyl cyclotransferase gliK to remove both gamma-glutamyl
CC moieties (PubMed:22903976, PubMed:24039048). Subsequent processing via
CC gliI yields a biosynthetic intermediate, which is N-methylated via the
CC N-methyltransferase gliN, before the gliotoxin oxidoreductase gliT-
CC mediated disulfide bridge closure (PubMed:20548963, PubMed:22936680,
CC PubMed:24039048, PubMed:25062268). GliN-mediated amide methylation
CC confers stability to ETP, damping the spontaneous formation of tri- and
CC tetrasulfides (PubMed:25062268). Intracellular dithiol gliotoxin
CC oxidized by gliT is subsequently effluxed by gliA (PubMed:26150413).
CC Gliotoxin contributes to pathogenesis during invasive aspergillosis
CC (PubMed:17601876, PubMed:18199036). In macrophages and neutrophils,
CC gliotoxin showed inhibition of various different cell functions
CC including cytokine production, antigen presentation, phagocytosis, and
CC production of reactive oxygen species (PubMed:17601876).
