CC -!- FUNCTION: Sphingosine N-acyltransferase-like protein; part of the gene
CC cluster that mediates the biosynthesis of fumonisins B1 (FB1), B2
CC (FB2), B3 (FB3), and B4 (FB4), which are carcinogenic mycotoxins
CC (PubMed:12620260). On the basis of the chemical structures of
CC fumonisins and precursor feeding studies, fumonisin biosynthesis is
CC predicted to include at least five groups of biochemical reactions:
CC synthesis of a linear polyketide with a single terminal carbonyl
CC function and methyl groups at C-10 and C-14; condensation of the
CC polyketide with alanine; reduction of the polyketide carbonyl to a
CC hydroxyl; hydroxylation of 2-4 polyketide carbons; and esterification
CC of six-carbon tricarboxylic acids to two of the hydroxyls
CC (PubMed:12620260). The biosynthesis starts with the polyketide synthase
CC FUM1-catalyzed carbon chain assembly from one molecule of acetyl CoA,
CC eight molecules of malonyl CoA, and two molecules of methionine
CC (PubMed:10413619). The C-18 polyketide chain is released from the
CC enzyme by a nucleophilic attack of a carbanion, which is derived from
CC R-carbon of alanine by decarboxylation, on the carbonyl carbon of
CC polyketide acyl chain (PubMed:15137825, PubMed:12720383). This step is
CC catalyzed by a pyridoxal 5'-phosphate-dependent aminoacyl transferase
CC FUM8 (PubMed:15137825, PubMed:12720383). The resultant 3-keto
CC intermediate 2-amino-3-oxo-12,16-dimethylicosane is then
CC stereospecifically reduced to the 3-hydroxyl product 2-amino-3-hydroxy-
CC 12,16-dimethylicosane by reductase FUM13 (PubMed:12720383,
CC PubMed:15137825). Subsequent oxidations at C-5, C-10, C-14 and C-15
CC followed by tricarballylic esterification of the hydroxyl groups on C-
CC 14 and C-15 furnish the biosynthesis of fumonisins (PubMed:15066782,
CC PubMed:15137825, PubMed:16489749). The C-10 hydroxylation is performed
CC by the cytochrome P450 monooxygenase FUM2 and occurs early in the
CC biosynthesis (PubMed:16536629). The C-5 hydroxylation is performed by
CC the dioxygenase FUM3 and occurs late in the biosynthesis
CC (PubMed:20237561, PubMed:15066782, PubMed:15137825, PubMed:16536629).
CC Cytochrome P450 monooxygenases FUM6 and FUM15 may be responsible for
CC the two remaining hydroxylations at positions C-14 and C-15
CC (PubMed:12620260). The FUM11 tricarboxylate transporter makes a
CC tricarboxylic acid precursor available for fumonisin biosynthesis via
CC its export from the mitochondria (PubMed:12620260). If the precursor is
CC citrate, the FUM7 dehydrogenase could remove the C-3 hydroxyl of
CC citrate to form tricarballylic acid either before or after the CoA
CC activation by the FUM10 acyl-CoA synthetase and FUM14 catalyzed
CC esterification of CoA-activated tricarballylic acid to the C-14 and C-
CC 15 hydroxyls of the fumonisin backbone (PubMed:16489749,
CC PubMed:17147424). Alternatively, if the precursor is cis-aconitate,
CC FUM7 may function to reduce the double bond (PubMed:17147424). In this
CC alternate proposal, feeding studies with tetradehydro-fumonisin B1
CC suggests that FUM7 cannot function on the tricarballylic ester and must
CC therefore act before the FUM14-mediated esterification
CC (PubMed:17147424). FUM18 is not required for production of fumonosins
CC but may have an indirect role such as self-protection
CC (PubMed:12620260). {ECO:0000269|PubMed:10413619,
