Part:BBa_K4239003

Enhanced luciferase substrate forming units fiatluxA

Description

fiatluxA is made to be used with fiatluxB (BBa_K239004). It codes for a subpart of the luciferase protein. With the subpart coding from fiatluxB, they form the luciferase protein.

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

The systeme fiatluxA/fiatluxB is made to be used with fiatluxC (BBa_K239001), fiatluxD (BBa_K239002) and fiatluxE (BBa_K239001), gathered in the fiatluxCDABE (BBa_K239006) operon.

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.
