How many initiator tRNA genes does Escherichia coli need?

Journal of bacteriology - 1 Jul 2014

Samhita Laasya, Nanjundiah Vidyanand, Varshney Umesh

Abstract excerpt

Multiple copies of a gene require enhanced investment on the part of the cell and, as such, call for an explanation. The observation that Escherichia coli has four copies of initiator tRNA (tRNAi) genes, encoding a special tRNA (tRNA(fMet)) required to start protein synthesis, is puzzling particularly because the cell appears to be unaffected by the removal of one copy. However, the fitness of an organism has...
