Function

CCR1_PETHY Involved in the latter stages of lignin biosynthesis (PubMed:24985707). Catalyzes one of the last steps of monolignol biosynthesis, the conversion of cinnamoyl-CoAs into their corresponding cinnamaldehydes (PubMed:25217505, PubMed:24985707). Mediates the conversion of feruloyl CoA to coniferylaldehyde (PubMed:25217505, PubMed:24985707). Also active toward p-coumaroyl-CoA and sinapoyl-CoA (PubMed:25217505, PubMed:24985707). Involved in the production of floral volatile phenylpropanoids in flowers of fragrant cultivars (e.g. cv. Mitchell and cv. V26) from cinnamic acid, a common precursor with the anthocyanin biosynthesis pathway involved in flower pigmentation (PubMed:24985707).^{[1] [2]}
