Enhanced luciferase substrate forming unit fiatluxB


Description

fiatluxB is made to be used with fiatluxA (BBa_K4239003). It codes for a subpart of the luciferase protein. With the subpart encoded by fiatluxA, they form the luciferase protein.

Luciferase has as substrates FMNH2, O2 and Fatty aldehydes, and produces H20, Fatty Acids and FMN and emits luminescence.

The system fiatluxA/fiatluxB is made to be used with fiatluxC (BBa_K4239001), fiatluxD (BBa_K4239002) and fiatluxE (BBa_K4239005), gathered in the fiatluxCDABE (BBa_K4239006) operon.

fiatlux genes come from ilux genes (C, D, A, B, E). They were modified to remove every iGEM restriction site (EcoRI, XbaI, SpeI and PstI) 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.

Construction

The ilux operon was available in a pGEX plasmid. fiatluxA, fiatluxB and fiatluxE were directly constructed together in fiatluxABE. iGEM restriction sites were successfully removed in the iluxABE genes by following these steps: DNA extraction, PCR directed mutagenesis, agarose gel analysis with green gel, and gel purification. A classical PCR was performed to reconstitute iluxABE fragments which had been cut by the restriction enzymes. The part is now called fiatluxABE. This part was then cloned and transformed in a pSB1C3 (already in iGEM biobrick format) and pBAD18 (high-copy vector with an arabinose inducible promoter) plasmid in E.coli DH5α. More details about the construction are on the following page fiatluxABE (BBa_K4239007).
