Inhibition of Cell Division Induced by External Guide Sequences (EGS Technology) Targeting ftsZ

Mostrar todas las versiones(3)

EGS (external guide sequence) technology is a promising approach to designing new antibiotics. EGSs are short antisense oligoribonucleotides that induce RNase P-mediated cleavage of a target RNA by forming a precursor tRNA-like complex. The ftsZ mRNA secondary structure was modeled and EGSs compleme...
