Abstract excerpt
The aarE1 allele was identified on the basis of the resulting phenotype of increased aminoglycoside resistance. The aarE1 mutation also resulted in a small-colony phenotype and decreased levels of aac(2')-Ia mRNA. The deduced AarE gene product displayed 61% amino acid identity to the Escherichia coli UbiA protein, an octaprenyltransferase required for the second step of ubiquinone biosynthesis. Complementation...
