J23100-RBS-phnJ_mut45-terminator
Use BBa_K823004-BBa_B0034 to express the mutant of C-P lyase, which can degrade the glyphosate, from Enterobacterales. This subunit is essential to the activity of the whole enzyme, improving 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 lysis. 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、RBS、Terminator(BBa_J23100、BBa_B0034、BBa_B0015) and the parts (phnJ_mut45)on the expression vector pSB1C3 by standard assembly. Then the ligation mixture was transformed into E. coli DH5α & E. coli BL21(DE3), which enables the E. coli to degrade glyphosate at higher efficiency and improves the binding ability with the endogenous PhnHIK.
