COMMENTARY 
LITERATURE
analysis
biofuel production
incorporation of curcumin and phenylpentanoids into lignin has a positive effect on saccharification yield after alkaline pretreatment. To design a lignin that is easier to degrade under alkaline conditions, curcumin (diferuloylmethane) is produced in the model plant Arabidopsis thaliana via simultaneous expression of the turmeric genes diketide-CoA synthase (DCS) and curcumin synthase 2 (CURS2). The transgenic plants produce a plethora of curcumin- and phenylpentanoid-derived compounds with no negative impact on growth. Catalytic hydrogenolysis gives evidence that both curcumin and phenylpentanoids are incorporated into the lignifying cell wall, thereby significantly increasing saccharification efficiency after alkaline pretreatment of the transgenic lines by 14-24% as compared with the wild type
synthesis
analysis
-
method for discriminating Curcuma species by intron length polymorphism markers in genes encoding diketide-CoA synthase and curcumin synthase. By applying this method, and constructing a dendrogram based on these markers, seven Curcuma species are clearly distinguishable and Curcuma longa specimens are geographically distinguishable
analysis
-
method to detect expression differences between species in detail, based on RNA sequencing analysis. The difference in the contents of curcuminoids among the species can be explained by the changes in the expression of genes encoding diketide-CoA synthase, and curcumin synthase at the branching point of the curcuminoid biosynthesis pathway
synthesis
-
construction of a fusion protein diketide-CoA synthase::curcumin synthase. Comparing to CURS, the fusion protein shows similar substrate specificities and catalytic potentials to catalyze the formation of various curcuminoids, with increased yields of curcuminoids
synthesis
production of curcuminoids using an engineered artificial pathway in Escherichia coli. Expression of Arabidopsis thaliana 4-coumaroyl-CoA ligase and Curcuma longa diketide-CoA synthase (DCS) and curcumin synthase (CURS1) leads to synthesis of 70 mg/l of curcumin from ferulic acid. Bisdemethoxycurcumin and demethoxycurcumin are produced, but in lower concentrations, by feeding 4-coumaric acid or a mixture of 4-coumaric acid and ferulic acid, respectively. To produce caffeic acid, tyrosine ammonia lyase from Rhodotorula glutinis and 4-coumarate 3-hydroxylase from Saccharothrix espanaensis are used. Caffeoyl-CoA 3-O-methyltransferase from Medicago sativa converts caffeoyl-CoA to feruloyl-CoA. Using caffeic acid, 4-coumaric acid or tyrosine as a substrate, 3.9, 0.3, and 0.2 mg/l of curcumin are produced, respectively
synthesis
a curcuminoid producing unnatural fusion protein diketide-CoA synthase:curcumin synthase is constructed. The fusion protein may contribute to further understand the biosynthesis of curcuminoids in ginger but also be advantage to further manipulate the biosynthesis of curcuminoid analogs, particularly including tetrahydrobisdemethoxycurcumin (THBDC) and various dihydrocurcuminoid derivatives in microorganisms
synthesis
biosynthetic pathway of p-coumaric acid, caffeic acid and curcumin in Escherichia coli can be triggered by using heat shock promoters, suggesting its potential for the development of new industrial bioprocesses or even new bacterial therapies. p-Coumaric acid is successfully produced from tyrosine and caffeic acid produced either from tyrosine or p-coumaric acid using tyrosine ammonia lyase (TAL) from Rhodotorula glutinis, 4-coumarate 3-hydroxylase (C3H) from Saccharothrix espanaensis or cytochrome P450 CYP199A2 from Rhodopseudomonas palustris. The highest p-coumaric acid production obtained is 2.5 mM. Caffeic acid production reaches 0.370 mM. 0.017 mM cumin is produced using 4-coumarate-CoA ligase (4CL1) from Arabidopsis thaliana, diketide-CoA synthase (DCS) and curcumin synthase 1 (CURS1) from Curcuma longa
synthesis
design, construction and optimization of a heterologous pathway to produce curcuminoids in Escherichia coli. This pathway involves six enzymes, tyrosine ammonia lyase (TAL), 4-coumarate 3-hydroxylase (C3H), caffeic acid O-methyltransferase (COMT), 4-coumarate-CoA ligase (4CL), diketide-CoA synthase (DCS), and curcumin synthase (CURS1). Curcumin production is enhanced and reachs 43.2 mM, corresponding to an improvement of 160% comparing to mono-culture system
synthesis
production of curcuminoids in engineered Escherichia coli. Two curcuminoids (dicinnamoylmethane and bisdemethoxycurcumin) are synthesized from glucose in Escherichia coli. PAL (phenylalanine ammonia lyase) or TAL (tyrosine ammonia lyase), along with Os4CL (p-coumaroyl-CoA ligase) and CUS (curcumin synthase) genes, are introduced into Escherichia coli, and each strain produces dicinnamoylmethane or bisdemethoxycurcumin, respectively. In order to increase the production of curcuminoids in Escherichia coli, the shikimic acid biosynthesis pathway, which increases the substrates for curcuminoid biosynthesis, is engineered. Using the engineered strains, the production of bisdemethoxycurcumin increases from 0.32 to 4.63 mg/l, and that of dicinnamoylmethane from 1.24 to 6.95 mg/l
