    Abstract:
    The possibility of creating artificial overlappons was studied on the model of two genes, that coding for the N-terminal part of lambda cro protein and the cat of E. coli. To test the dependence of translational coupling efficiency on the intercistronic region a series of recombinant DNA molecules carrying different hybrid operons with partially overlapping genes was constructed. The translational efficiency of the distal to the promoter gene was shown to depend on the intercistronic region structure: overlapping of the AUG codon with the terminating one of the proximal gene in the UGAUG manner is optimal for the translational coupling, and the displacement of AUG at several nucleotides in both directions decreases the translational reinitiation efficiency for the ribosomes, that have synthesised the first gene product.
