In Vivo Production of Five Crocins in the Engineered Escherichia coli
ACS Synth Biol 2020 May 15;9(5):1160-1168.PMID:32216376DOI:10.1021/acssynbio.0c00039.
Crocins are highly valuable medicinal compounds for treating human disorders, and they also serve as spices and coloring agents. However, the supply of crocins from plant extractions is insufficient for current demands, and using synthetic biology to produce crocins remains a big challenge. Here, we report the in vivo production of five types of crocins in E. coli with GjUGT94E13 and GjUGT74F8, which are responsible for the glycosylation of crocetin, from the crocin-producing plant Gardenia jasminoides. Subsequently, native UDP-glucose biosynthesis in E. coli is strengthened by the overexpression of pgm and galU. The optimization of catalytic reactions has demonstrated that 50 mM NaH2PO4-Na2HPO4 buffer (pH 8.0) plus 5% glucose is the best medium to use for the efficient glycosylation of crocetin. In engineered E. coli, the conversion rate of Crocin III and crocin V from crocetin (50 mg/L) by the catalysis of GjUGT74F8 was increased to 66.1%, and the conversion rate of five types of crocins from crocetin (50 mg/L) via GjUGT94E13 and GjUGT74F8 was 59.6%, much higher than the catalytic activity of the reported microbial UGTs. This study not only sheds light on the in vivo biosynthesis of crocins in E. coli, but also provides important genetic tools for the de novo synthesis of crocins.
[Determination of Six Ingredients in Gardenia jaminoides Fruits with Quantitative Analysis of Muti-components by Single Marker]
Zhong Yao Cai 2015 Mar;38(3):531-5.PMID:26495656doi
Objective: To establish a method of quantitative analysis of multi-components, by single marker(QAMS)for simultaneously determining six ingredients in Gardenia jasminoides fruits. Methods: A multi-wavelength segmentation detection method was used. A methodological mode was found to analysis six ingredients in Gardenia jasminoides fruits by quantitative analysis of QAMS. Taken geniposide as reference to create RCF with gardenia acid, chlorogenic acid, crocin I, crocin II and Crocin III. Results: The good reproducibility and acceptable durability of method was validated between two HPLC systems and three columns. 20 batches of Gardenia jaminoides fruits was analysis, and the results showed good linear correlation compared to external standard method (r > 0. 999). Conclusion: QAMS can be used as quality evaluation method of multi-component Gardenia jaminoides fruits.
