IUBMB Comments
A polyketide synthase from the plant Curcuma longa (turmeric). Three isoforms exist, CURS1, CURS2 and CURS3. While CURS1 and CURS2 prefer feruloyl-CoA as a starter substrate, CURS3 can accept 4-coumaroyl-CoA equally well (see EC 2.3.1.219, demethoxycurcumin synthase).

LITERATURE
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
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
