Abstract
Five kinds of promoters were evaluated as tools for regulated gene expression in the PHA-producing bacterium Cupriavidus necator. Several broad-host-range expression vectors were constructed by which expression of a reporter gene gfp was controlled by P lac , P tac , or P BAD derived from Escherichia coli, or promoter regions of phaC1 (P phaC ) or phaP1 (P phaP ) derived from C. necator. Then, the gfp-expression profiles were determined in C. necator strains harboring the constructed vectors when the cells were grown on fructose or soybean oil. P lac , P tac , P phaC , and P phaP mediated constitutive gene expression, among which P tac was the strongest promoter. lacI-P tac was not thoroughly functional even after addition of isopropyl-β-d-thiogalactopyranoside (IPTG), probably due to inability of C. necator to uptake IPTG. Gene expression by araC-P BAD could be regulated by varying l-arabinose concentration in the medium, although P(3HB) production rate was slightly decreased in the recombinant. phaR-P phaP exhibited an expression profile tightly coupled with P(3HB) accumulation, suggesting application of the vector harboring phaR-P phaP for gene expression specific at the PHA-biosynthesis phase. The properties of these promoters were expected to be useful for effective engineering of PHA biosynthesis in C. necator.
