Gentamicin Resistance Gene

Introduction

Gentamicin is an aminoglycoside frequently used in clinical settings to treat many bacterial infections. A gentamicin resistance gene can confer resistance to aminoglycosides based on several mechanisms: enzymatic inactivation of aminoglycosides, increased efflux from the bacterial cell, interfering with binding domains of aminoglycosides, etc.

Usage and Biology

Usage and Biology:

This part is the coding segment of the Gentamicin Resistance gene which is used within the plasmid BBa_K4235002 and it confers resistance to gentamicin. The expression of the gentamicin coding sequence is driven by the pC promoter BBa_K4235004. This circuit is also a part of the mini-attTn7 transposon segment BBa_K4235010, used in the Bac-to-Bac expression system by Stony_Brook 2021.

This marker is used to provide gentamicin resistance to the pFastBac vector during the transposition in the Bacmid, propagated in E coli DH10Bac cells. A concentration of 7 ug/ml gentamicin is recommended for transposition.

This Gentamicin resistance gene is part of the original plasmid pFastBac, which was a kind gift from the Airola lab at Stony Brook University.
