A synthetic codon-optimized EFE-gene encoding ethylene forming enzyme for Synechocystis sp. PCC6803
Overview
A synthetic codon-optimized EFE-gene encoding EFE for Synechocystis sp. PCC6803. The modified EFE gene codes for Ethylene forming enzyme, which enables the conversion of intracellular 2-oxoglutarate into ethylene, which can be quantitatively measured by gas chromatography (GC). The EFE-gene can thus be utilized as a reporter gene.
Design Notes
The gene has been codon-optimized to work in Synechocystis sp. PCC6803. The sequence is modified with overhangs for position 5 to fit a type IIs assembly with 7 fragments using BbsI. BbsI site removed from EFE. The stop codon is included in the gene sequence. One codon has been changed to GAG from GAA to avoid an illegal restriction site (Sap1).
NOTE! The starting codon ATG has been removed to be compatible with our composite part (reading frame shift).
