CYP6G1

CYP6G1

CYP6G1 is a cytochrome p450 enzyme found in the common fruit fly, Drosophila melanogaster. Able to efficiently Hydroxylate imidacloprid at the 4th and 5th carbons, it is capable of bestowing protective properties to organisms that can express it.

Background of CYP6G1

As an enzyme capable of hydroxylating the 4 and 5 carbons of imidacloprid, it is capable of bestowing a significant protective effect to insects harboring this gene. It has an affinity to 6OH imidacloprid, allowing it to gnerate 4,5 OH imidacloprid [1], which has an ld50 of over 1 microgram vs 57 nanograms for imidacloprid [2]. Used in conjunction with CYP6CM1vQ, (BBa_K1813003) it can be extremely effective in bestowing imidacloprid resistance to an organism.
This coding sequence was synthesized and is codon optimized for E. coli. It was originally identified in Drosophila melanogaster, the common fruitfly [1]. This part is also used in BBa_K1613003 and BBa_K1813012
