Objective We explored the co-localization of multiple enzymes on a DNA backbone via a DNA-binding protein, Gene-A* (A*-tag) to increase the efficiency of cascade enzymatic reactions. Results Firefly luciferase (FLuc) and pyruvate orthophosphate dikinase (PPDK) were genetically fused with A*-tag and modified with single-stranded (ss) DNA via A*-tag. The components were assembled on ssDNA by hybridization,...
The feasibility of assembling enzymes, catalyzing consecutive reactions, on to a double-stranded DNA (dsDNA) scaffold utilizing zinc finger motifs is described. The catalytic activities of two zinc finger motif-fused enzymes catalyzing a bioluminescence reaction with energy recycling, namely pyruvate phosphate dikinase and firefly luciferase, have been evaluated. Bioluminescence measurements with...
