CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of tenellin-type 2-pyridones, iron-chelating
CC compounds involved in iron stress tolerance, competition with the
CC natural competitor fungus Metarhizium robertsii and insect hosts
CC infection (PubMed:17216664, PubMed:19067514, PubMed:20575135,
CC PubMed:34903054). TenA catalyzes an oxidative ring expansion of
CC pretenellin A and 14-hydropretellenin A to form the 2-pyridone core,
CC leading to the production of pretenellin B and pyridovericin,
CC respectively (PubMed:19067514, PubMed:34903054). The pathway begins
CC with the assembly of the polyketide-amino acid backbone by the hybrid
CC PKS-NRPS tenS with the help of the enoyl reductase tenC. These enzymes
CC catalyze the synthesis of the pyrrolidine-2-dione intermediates
CC pretellinin A, 11-hydropretellenin A, 12-hydropretellenin A, 13-
CC hydropretellenin A, 14-hydropretellenin A, 12-oxopretellenin A and
CC prototellinin D. The cytochrome P450 monooxygenase tenA then catalyzes
CC an oxidative ring expansion of pretenellin A and 14-hydropretellenin A
CC to form the 2-pyridone core, leading to pretenellin B and
CC pyridovericin, respectively. The cytochrome P450 monooxygenase tenB is
CC then required for the selective N-hydroxylation of the 2-pyridone
CC nitrogen of yield tellinin and 15-hydroxytellenin (15-HT),
CC respectively. The UDP-glucosyltransferase GT1 and the methyltransferase
CC MT1, located outside the tenS gene cluster, contribute to the stepwise
CC glycosylation and methylation of 15-HT to obtain the glycoside
CC pyridovericin-N-O-(4-O-methyl-beta-D-glucopyranoside) (PMGP).
CC Additional related compounds such as 1-O-methyl-15-HT, (8Z)-1-O-methyl-
CC 15-HT, and O-methyltenellin A are also produced but the enzymes
CC involved in their biosynthesis have still to be determined
CC (PubMed:34903054). {ECO:0000269|PubMed:17216664,

CC -!- COFACTOR:
CC Name=heme; Xref=ChEBI:CHEBI:30413;
CC Evidence={ECO:0000250|UniProtKB:P04798};
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000269|PubMed:17216664, ECO:0000269|PubMed:19067514,
CC ECO:0000269|PubMed:20575135, ECO:0000269|PubMed:34903054}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC protein {ECO:0000255}.
CC -!- INDUCTION: Expression is positively regulated by the cluster-specific
CC transcription factor tenR and is induced during cocultures with the
CC natural competitor fungus Metarhizium robertsii.
CC {ECO:0000269|PubMed:34903054}.
CC -!- DISRUPTION PHENOTYPE: Fails to produce tenellin, and leads to the
CC accumulation of 11-hydropretellenin A, 12-hydropretellenin A, 13-
CC hydropretellenin A, 14-hydropretellenin A, 12-oxopretellenin A and
CC prototellinin D. {ECO:0000269|PubMed:19067514,
CC ECO:0000269|PubMed:34903054}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
