Furthermore, the improved pathway is able to convert > 50% of fed l-tyrosine to caffeic acid (Additional file 1: Figure S1A), which indicates that it should be able to produce high amounts of caffeic acid in a tyrosine-producer strain. Lastly, we tested whether additional copies of the palustrisredoxin encoding gene, pux, would further improve the performance of the so far best pathway configuration with FjTAL and the natural redox partners of CYP199A2 F185L N∆7 (Pux/PuR redox system). Bakkes PJ, Riehm JL, Sagadin T, Rühlmann A, Schubert P, Biemann S, et al. The in vitro studies showed that tethered redox complexes are able to overcome the need to use an excess of redox partners over the Cytochrome P450 enzyme, to compensate for low protein–protein affinities (typically a five- to 20-fold molar excess of ferredoxin is used in vitro). The molecular structure of the compound was found to have E isomer configuration. Cite this article. Commercially available 3,4-dihydroxybenzoic acid (3,4-DHB, 16) was used for the synthesis of caffeic acid ester analogs 20, 21 in which no carbon separates the carbonyl group from the catechol moiety.

A new method for the preparation of caffeic acid esters was investigated. Overall, with the exchange of RgTAL for FjTAL and the change of the redox system from Pux/PdR to Pux/PuR with an additional gene copy of pux, we improved this recombinant pathway and were able to produce caffeic acid from glucose without feeding l-tyrosine. 10 µL of the samples were analyzed by reversed-phase HPLC (instrument: Agilent 1100, column: Agilent Zorbax Eclipse XDB-C18 80Å, 4.6 × 150 mm, 5 µm; detector: Agilent diode array detector G1315B, λ = 310 nm, gradient: 10% to 20% Acetonitrile with 0.1% Trifluoracetic acid over 17 min. Therefore, we are inclined to suggest that the tyrosine ammonia lyase has lost its activity by that time. It is possible that rearranging the genes in the vector system could lead to even better results than described herein; however, exploring the combinatorial space of enzyme expression levels in this pathway is beyond the scope of this study. Potential pharmacology. Rodriguez A, Kildegaard KR, Li M, Borodina I, Nielsen J. PubMed Central  The datasets used and/or analyzed during the current study are available from the corresponding author on reasonable request. Sariaslani FS. This suggests that the electron transfer from ferredoxin to CYP199A2 F185L N∆7 is severely impaired with the surrogate ferredoxin Pdx, whereas the electron transfer from PdR to Pux in the hybrid system appears to sufficiently support substrate turnover.

It is readily produced in plants as … The key feature of this synthesis is the Verley–Doebner modification of the Knoevenagel condensation of the p-hydroxyphenyl malonate intermediate. Department of Biotechnology, Bioenergy Research Center, Chonnam National University, Gwangju, Korea. Metab Eng. The low abundance of these compounds and their occurrence in complex mixtures of variable composition in plants, makes recombinant microbial cell factories an attractive source for industrial applications. However, when we applied tethering strategies to increase the affinity of the Cytochrome P450 and the redox partners towards each other, we observed higher titers with the non-natural redox partners. Plasmids and strains used in fermentations are described in Tables 1 and 2, respectively. This titer is slightly higher than the titers reported for the HpaBC-based pathways in wildtype E. coli with glucose as the only carbon source [17, 19]. A bow angle was revealed in the longer ester group. Watts KT, Lee PC, Schmidt-Dannert C. Exploring recombinant flavonoid biosynthesis in metabolically engineered Escherichia coli. 2013;110:1858–64. This could be caused by the lack of available l-tyrosine once the cultures reach stationary phase, although we did not observe increased titers when spiking the cultures with 3 mM l-tyrosine at 48 h p. i. Biotechnol Bioeng. https://doi.org/10.1016/s0167-4838(98)00017-x. Finally, CAPE (caffeic acid phenylethyl ester) quenched the free radicals as a phenolic antioxidant.

We observed the highest titers for the natural redox system (s05) and virtually no activity with the full surrogate system composed of Pdx/PdR (Fig. Biochem Biophys Acta. 2017;125:41–9. Caffeic acid, which is unrelated to caffeine, is biosynthesized by hydroxylation of coumaroyl ester of quinic acid (esterified through a side chain alcohol). This may indicate that the metabolic burden of expressing the PCNA subunits in addition to the pathway enzymes and the three resistance genes required for plasmid maintenance represents a disadvantage of the strains expressing the tethered Cytochrome P450 complexes compared to the ones expressing the free, natural redox complex (s15 and s18). Optional: p-coumaric acid (from fresh 100× stock in MeOH, final 3 mM) or l-tyrosine (from fresh 100x stock in 1 M HCl).
