Abstract excerpt
The gene for RsuA, the pseudouridine synthase that converts U516 to pseudouridine in 16S ribosomal RNA of Escherichia coli, has been deleted in strains MG1655 and BL21/DE3. Deletion of this gene resulted in the specific loss of pseudouridine516 in both cell lines, and replacement of the gene in trans on a plasmid restored the pseudouridine. Therefore, rsuA is the only gene in E. coli with the ability to produce a...
