crtE and crtB in a single open reading frame

This part contains the sequences of crtE and crtB connected by a short linker sequence. The stop codon of each gene has been removed to express the genes in a single open reading frame. The enzymes encoded by the genes supply the precursor of carotenoids when expressed in Escherichia coli.

The composite part was made by fusing crtEB (BBa_K2971010) and crtI (BBa_K2971001) via Gibson cloning. The part was then transformed into competent cells of E. coli. The presence of the insert was screened with colony pcr (figure 2). The colony with the insert was analyzed by sequencing to check for potential mutations or frame-shifts.

Only one colony (1) showed the presence of the correct insert. 1 was then further investigated.
