CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of the mycotoxin lucilactaene and the
CC lucilactaene-related compound NG-391 that act as cell cycle inhibitors
CC with potent growth inhibitory activity against malarial parasites,
CC moderate growth inhibitory activity against cancer cells, and no
CC activity against bacteria and fungi (PubMed:32043422). Within the
CC cluster, LUC5, LUC6, LUC2 and LUC1 are sufficient for lucilactaene
CC production (By similarity). The roles of the other LUC members are yet
CC undetermined (By similarity). The hybrid PKS-NRPS synthetase LUC5 is
CC responsible for the condensation of one acetyl-coenzyme A (CoA) unit
CC with six malonyl-CoA units and the amide linkage of the arising
CC heptaketide and homoserine, subsequently releasing the first
CC intermediate, as an alcohol with an open ring structure (By
CC similarity). Lucilactaene and NG-391 lack the 7-methyl group present in
CC fusarins which is inserted in fusarins by the C-methyltransferase
CC (CMeT) domain of the fusarin synthetase FUS1, suggesting that the CMet
CC domain of LUC5 does not methylate this position (Probable). The
CC cytochrome P450 monooxygenase LUC2 participates in multiple oxidation
CC processes at carbon C-20 and is able to use the LUC5 product as
CC substrate (By similarity). This reaction seems to be essential before
CC the 2-pyrrolidone ring closure can be catalyzed by LUC6 (By
CC similarity). LUC2 is able to further oxidizes carbon C-20 after ring
CC closure, resulting in the formation of demethyllucilactaene (By
CC similarity). As the last step, the methyltransferase LUC1 methylates
CC the hydroxyl group at C-21 to generate lucilactaene (PubMed:32043422).
