Description
Coenzyme Q (CoQ) is composed of a benzoquinone moiety and an isoprenoid side chain of varying lengths. The length of the side chain is controlled by polyprenyl diphosphate synthase. In this study, dps1 genes encoding decaprenyl diphosphate synthase were cloned from three fungi: Bulleromyces albus, Saitoella complicata, and Rhodotorula minuta. The predicted Dps1 proteins contained seven conserved domains found in typical polyprenyl diphosphate synthases, and were 528, 440, and 537 amino acids in length in B. albus, S. complicata, and R. minuta, respectively. E. coli expressing the fungal dps1 genes produced CoQ10 in addition to endogenous CoQ8. Two of the three fungal dps1 genes (from S. complicata and R. minuta) were able to replace the function of ispB in an E. coli mutant strain. In vitro enzymatic activities were also detected in recombinant strains. The three dps1 genes were able to complement an S. pombe dps1, dlp1 double mutant. Recombinant S. pombe produced mainly CoQ10, indicating that the introduced genes were independently functional and did not require dlp1. The cloning of dps1 genes from various fungi has the potential to enhance production of CoQ10 in other organisms.
