pT7-ppk1(K.oralis)

Polyphosphate kinase (ppk1) (E.C. 2.7.4.1) catalyzes the formation of polyphosphate from ATP. In BBa_K1217003, ppk1 was under the control of T7 promotor. Under iptg induction, over-expression of ppk1 can reduce the phosphate level in the medium by its incorporation into polyphosphate synthesis inside the bacteria.

Usage and Biology

Expression of ppk1 enzyme

SDS-PAGE analysis of expression of K.oralis PPK1 enzyme inside E.coli. Expression of PPK1 is induced by 0.5mM IPTG at 30 degree for 5 hours. Band marked with star is the PPK1 enzyme, the enzyme expressed is soluble.

Efficiency of this construct is compared with Two other design BBa_
