Improving bioluminescence of a minimal luciferase by adding a charged oligopeptide: picALuc2.0
Abstract: Luciferases are widely used as reporter proteins in diverse fields from basic biology to medical and environmental researches. Development of luciferase applications for reporter proteins requires small size without target inhibition, appropriate genomic insertion for high expression level, and bright emission for detection sensitivity. We previously developed the minimal luciferase picALuc, but its luminescence was still dim compared to other bright luciferases in terms of expression in Escherichia coli. In this study, diverse additions of oligopeptides with charged residues (eight amino acids in total) to the C‐terminus of picALuc enhanced luminescence by up to approximately 50‐fold, that is, enhanced enzymatic activity. Moreover, these high luminescence activities were achieved in bacterial and mammalian expression, suggesting their further applicability in many expression systems. The finding in this study that the simple addition of oligopeptides with charged residues (or charge engineering of this kind) enhances enzymatic activity may be applied to a wide variety of enzymatic reactions and protein functions.
