CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that CC mediates the biosynthesis of mycophenolic acid (MPA), the first CC isolated antibiotic natural product in the world obtained from a CC culture of Penicillium brevicompactum in 1893 (PubMed:26751579). MpaDE CC is an endoplasmic reticulum-bound entyme that catalyzes the conversion CC of 5-methylorsellinic acid (5MOA) into the phthalide compound 5,7- CC dihydroxy-4,6-dimethylphthalide (DHMP) (PubMed:26751579). MpaDE first CC catalyzes hydroxylation of 5-MOA to 4,6-dihydroxy-2-(hydroxymethyl)-3- CC methylbenzoic acid (DHMB), and then acts as a lactone synthase that CC catalyzes the ring closure to convert DHMB into DHMP (PubMed:26751579). CC The first step of the pathway is the synthesis of 5-methylorsellinic CC acid (5MOA) by the cytosolic polyketide synthase mpaC. 5MOA is then CC converted to the phthalide compound 5,7-dihydroxy-4,6-dimethylphthalide CC (DHMP) by the endoplasmic reticulum-bound cytochrome P450 monooxygenase CC mpaDE. MpaDE first catalyzes hydroxylation of 5-MOA to 4,6-dihydroxy-2- CC (hydroxymethyl)-3-methylbenzoic acid (DHMB). MpaDE then acts as a CC lactone synthase that catalyzes the ring closure to convert DHMB into CC DHMP. The next step is the prenylation of DHMP by the Golgi apparatus- CC associated prenyltransferase mpaA to yield farnesyl-DHMP (FDHMP). The CC ER-bound oxygenase mpaB then mediates the oxidative cleavage the C19- CC C20 double bond in FDHMP to yield FDHMP-3C via a mycophenolic aldehyde CC intermediate. The O-methyltransferase mpaG catalyzes the methylation of CC FDHMP-3C to yield MFDHMP-3C. After the cytosolic methylation of FDHMP- CC 3C, MFDHMP-3C enters into peroxisomes probably via free diffusion due CC to its low molecular weight. Upon a peroxisomal CoA ligation reaction, CC catalyzed by a beta-oxidation component enzyme acyl-CoA ligase ACL891, CC MFDHMP-3C-CoA would then be restricted to peroxisomes for the following CC beta-oxidation pathway steps. The peroxisomal beta-oxidation machinery CC than converts MFDHMP-3C-CoA into MPA_CoA, via a beta-oxidation chain- CC shortening process. Finally mpaH acts as a peroxisomal acyl-CoA CC hydrolase with high substrate specificity toward MPA-CoA to release the CC final product MPA (PubMed:26751579) (Probable).
