Enzymes involved in its biosynthesis pathway, as identified through functional expression and protein modeling: Squalene epoxidases (SQE), Cucurbitadienol synthase (CDS), Epoxide hydrolase (EPH3), Cytochrome P450 monooxygenase (CYP87D18), and UDP-glucosyltransferases (UGT720-269-1, UGT94 family). Docking studies indicated calculated binding affinities of -12.3 kcal/mol for cucurbitadienol and -12.5 kcal/mol for 24,25-epoxycucurbitadienol to CDS. [1]

| ln Vitro |
A large-scale functional expression survey of nearly 200 candidate genes was conducted to identify the enzymes responsible for mogroside V biosynthesis. This involved heterologous expression in yeast (Saccharomyces cerevisiae) and bacteria (Escherichia coli) systems to demonstrate the catalytic activity of SQE, CDS, EPH, CYP450s, and UGTs in converting substrates along the mogroside pathway. [1]
Metabolite analysis of developing Siraitia grosvenorii fruit showed that mogroside V (M5) is the major sweet component in ripe fruit (103 days after anthesis, DAA), accumulating at the expense of earlier glycosylated forms (M4 compounds) during the final stages of ripening. [1] |
| Enzyme Assay |
For squalene epoxidase (SQE) and cucurbitadienol synthase (CDS) activity, genes were cloned into yeast expression vectors (e.g., pESC-URA) and transformed into the yeast strain GIL77 (erg7 mutant). Transformed yeast was cultured, induced with galactose, and metabolites were extracted using organic solvents (e.g., n-hexane). The extracts were analyzed by liquid chromatography-mass spectrometry (LC-MS) to identify products like cucurbitadienol and 24,25-epoxycucurbitadienol. [1]
For cytochrome P450 (CYP) hydroxylase activity, candidate CYP genes were co-expressed with CDS and a NADPH-CYP reductase in yeast strain BY4743_YHR072. In some experiments, the lanosterol synthase inhibitor RO 48-8071 was added to shunt flux toward the mogroside pathway. Cells were lysed, extracted with ethyl acetate, and analyzed by LC-MS to detect hydroxylated intermediates like 11-hydroxycucurbitadienol and the final aglycone mogrol. [1] For UDP-glucosyltransferase (UGT) activity, UGT genes were expressed in E. coli as His-tagged proteins. Crude enzyme extracts were incubated with mogrol or various mogroside substrates (dissolved in DMSO) and UDP-glucose in a Tris-HCl buffer. After overnight incubation, reactions were stopped with methanol, centrifuged, and products were analyzed by LC-MS to identify glucosylated derivatives. [1] |

| Additional Infomation |
Mogroside IIIA is a β-D-glucoside and also a mogroside. It is a plant metabolite functionally related to mogrosides II-E. Mogroside III has been reported in Siraitia grosvenorii, and relevant data are available. Mogroside V is a triterpenoid glycoside natural sweetener isolated from the mature fruit of Siraitia grosvenorii. It is approximately 250 times sweeter than sucrose and contains no calories. [1]
Its biosynthetic pathway involves five major enzyme families: 1) Squalene epoxidase (SQE) epoxidizes squalene to 2,3;22,23-diepoxysqualene; 2) Cucurbita diol synthase (CDS) cyclizes diepoxysqualene to 24,25-epoxycucurbita diol; 3) Epoxide hydrolase (EPH3) hydrolyzes the epoxide at C24 and C25 to generate 24,25-dihydroxycucurbita diol; 4) Cytochrome P450 (CYP87D18) hydroxylates at C11; 5) UDP-glucosyltransferase (mainly UGT720-269-1) sequentially glucosylates the C24 and C3 positions of mogroside to generate diglucosylated M2, which is further branched by UGT94 family enzymes to generate pentaglucosylated mogroside V. [1] This study found that the genes encoding this pathway are not physically clustered in the genome, but rather exhibit a highly coordinated transcriptional pattern in young Syradia fruits, which is unique compared to other Cucurbitaceae plants. This coordinated expression is key to the evolution of this sweetener pathway. [1] |
