gene efe, recombinant enzyme expression in Synechocystis sp. strain PCC 6803, stable ethylene production through the integration of a codon-optimized version of the efe gene under control of the Ptrc promoter and the core Shine-Dalgarno sequence (5'-AGGAGG-3) as the ribosome-binding site, at the slr0168 neutral site. Increase in ethylene production is achieved twofold by RBS screening, improvement of ethylene production from a single gene copy of efe, using multiple tandem promoters and by putting our best construct on an RSF1010-based broad-hostself-replicating plasmid, which has a higher copy number than the genome | Pseudomonas savastanoi pv. phaseolicola |

additional information | construction of a glycogen-synthesis knockout mutant (DELTAglgC) to raise the intracellular amounts of the key Efe substrate, 2-oxoglutarate, from which ethylene is formed. Introduction of the ethylene biosynthetic pathway in mutant DELTAglgC. Under nitrogen limiting conditions, the glycogen knockout strain has increased intracellular 2-oxoglutarate levels, but the ethylene production is lower in the mutant strain than in the wild-type strain | Pseudomonas savastanoi pv. phaseolicola |
