CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of fumonisins B1 (FB1), B2 (FB2), B3 (FB3),
CC and B4 (FB4), which are carcinogenic mycotoxins (PubMed:16536629,
CC PubMed:12620260). On the basis of the chemical structures of fumonisins
CC and precursor feeding studies, fumonisin biosynthesis is predicted to
CC include at least five groups of biochemical reactions: synthesis of a
CC linear polyketide with a single terminal carbonyl function and methyl
CC groups at C-10 and C-14; condensation of the polyketide with alanine;
CC reduction of the polyketide carbonyl to a hydroxyl; hydroxylation of 2-
CC 4 polyketide carbons; and esterification of six-carbon tricarboxylic
CC acids to two of the hydroxyls (PubMed:12620260). The biosynthesis
CC starts with the polyketide synthase FUM1-catalyzed carbon chain
CC assembly from one molecule of acetyl CoA, eight molecules of malonyl
CC CoA, and two molecules of methionine (PubMed:10413619). The C-18
CC polyketide chain is released from the enzyme by a nucleophilic attack
CC of a carbanion, which is derived from R-carbon of alanine by
CC decarboxylation, on the carbonyl carbon of polyketide acyl chain
CC (PubMed:15137825, PubMed:12720383). This step is catalyzed by a
CC pyridoxal 5'-phosphate-dependent aminoacyl transferase FUM8
CC (PubMed:15137825, PubMed:12720383). The resultant 3-keto intermediate
CC 2-amino-3-oxo-12,16-dimethylicosane is then stereospecifically reduced
CC to the 3-hydroxyl product 2-amino-3-hydroxy-12,16-dimethylicosane by
CC reductase FUM13 (PubMed:12720383, PubMed:15137825). Subsequent
CC oxidations at C-5, C-10, C-14 and C-15 followed by tricarballylic
CC esterification of the hydroxyl groups on C-14 and C-15 furnish the
CC biosynthesis of fumonisins (PubMed:15066782, PubMed:15137825,
CC PubMed:16489749). The C-10 hydroxylation is performed by the cytochrome
CC P450 monooxygenase FUM2 and occurs early in the biosynthesis
CC (PubMed:16536629). The C-5 hydroxylation is performed by the
CC dioxygenase FUM3 and occurs late in the biosynthesis (PubMed:20237561,
CC PubMed:15066782, PubMed:15137825, PubMed:16536629). Cytochrome P450
CC monooxygenases FUM6 and FUM15 may be responsible for the two remaining
CC hydroxylations at positions C-14 and C-15 (PubMed:12620260). The FUM11
CC tricarboxylate transporter makes a tricarboxylic acid precursor
CC available for fumonisin biosynthesis via its export from the
CC mitochondria (PubMed:12620260). If the precursor is citrate, the FUM7
CC dehydrogenase could remove the C-3 hydroxyl of citrate to form
CC tricarballylic acid either before or after the CoA activation by the
CC FUM10 acyl-CoA synthetase and FUM14 catalyzed esterification of CoA-
CC activated tricarballylic acid to the C-14 and C-15 hydroxyls of the
CC fumonisin backbone (PubMed:16489749, PubMed:17147424). Alternatively,
CC if the precursor is cis-aconitate, FUM7 may function to reduce the
CC double bond (PubMed:17147424). In this alternate proposal, feeding
CC studies with tetradehydro-fumonisin B1 suggests that FUM7 cannot
CC function on the tricarballylic ester and must therefore act before the
CC FUM14-mediated esterification (PubMed:17147424).
