Enhanced luciferase substrate forming subunits fiatluxCD and the promoter J23117


Description

fiatluxC and fiatluxD are made to be used with fiatluxE. They code for a fatty acid reductase. With the subparts coding from fiatluxE, they form a complex that recycles fatty acids to fatty aldehydes. Fatty aldehydes will be used as a substrat for the luciferase protein.

The systeme fiatluxC/fiatluxD/fiatluxE is made to be used with fiatluxA and fiatluxB, gathered in the fiatluxCDABE operon. fiatluxA and fiatluxB code for the luciferase protein

Fiatlux genes come from ilux genes (C, D, A, B, E). They were modified to remove every Igem restriction site (EcoR1, Xba1, Spe1 and Pst1) included in genes. They were also adapted to include the biobrick format.

The ilux operon was born from a mutated natural luminescence operon present in the bacteria P.luminescens: the lux operon. These mutations were error-prone PCR induced according to Gregor et al.’s study in 2018 (Gregor et al. 2018). The aim was to create a system of genes that produced more light than the lux system.

Construction

FiatluxCD was directly synthesized with the promoter J23117 (BBa_J23117). It is a constitutive and weak promoter, so no inducer needs to be added. FiatluxCD and their promoter were ordered in the plasmid pACYDuet-1, a p15A low-copy plasmid, and transformed it into E.coli DH5α.
