Background

ATCCR1 is a Cinnamoyl CoA reductase found in Artabidopsis thaliana it functions to reduce the cinnamoyl coA molecule into cinnamaldehyde by utilizing the favourable kinetics offered by releasing the coA group. This enzyme belongs to the oxioreductase family and is involved in both the phenylpropanoid pathway and thus in the degradation of lignin.

Experimental Data

The genes encoding PAL (BBa_K1129003), 4-Cinnamic acid ligase(BBa_K1129042) and a Cinnamoyl Co-A reductase(BBa_1129005) were assembled into one PSB1C3 plasmid under constitutive promoters and transformed into E. coli. E.coli 10G cells were grown over night before being incubated with L-Phenylalanine for 7 hours, the sample was extracted before it was run on GC-MS.

The first two panels show experimental data for our PAL (Enc-P) expressed from PSB1C3, under constitutive promoters alone. The last panel shows experimental data for the entire biosynthetic pathway for the generation of cinnamaldehyde.

Figure 1. Compound generation identification by GC-MS. Chromatograms (left) and mass spectra (right) for select peaks are shown. Structures represent predictions based on library matching or comparison to standards. Controls represent plasmids missing the gene of interest. Top) GC-MS of a Cinnamic acid (10.580) control. Bottom) Conversion of Phenylalanine to Cinnamaldehyde (11.819) through the cinnamic acid intermediate(10.580) via the EncP, 4CL, and ATCCR1 gene construct under a constitutive promoter. The mass spec data shows a highly oxidized cinnamaldehyde that may have resulted from poor sample preparation
