phnJ_mut45

The mutant of C-P lyase, which can degrade the glyphosate, from Enterobacterales. This subunit is essential to the activity of the whole enzyme.Use K823004 to construct a new part that can improve the capability of chassis bacteria to degrade glyphosate.

Biology

Phn system is a gene cluster for organophosphorus transport and degradation in many microorganisms. Enterobacterales use phnHIJK genes to encode C-P lyase, PhnJ protein is an essential subunit that can crack C-P bond. The 45th proline was mutated to glutamine.

Usage

We ligased the strong promoter (BBa_J23100) and the parts (RBS-phnJ_mut45-Terminator) on the expression vector pSB1C3 by standard assembly. Then the ligation mixture was transformed into E. coli DH5α & E. coli BL21(DE3), enabled the E. coli to degrade glyphosate at higher efficiency and improved the binding ability with the endogenous PhnHIK.
