N(7)-Methylguanine at position 46 (m(7)G46) in tRNA from Thermus thermophilus is required for cell viability at high temperatures through a tRNA modification network

N(7)-methylguanine at position 46 (m(7)G46) in tRNA is produced by tRNA (m(7)G46) methyltransferase (TrmB). To clarify the role of this modification, we made a trmB gene disruptant (ΔtrmB) of Thermus thermophilus, an extreme thermophilic eubacterium. The absence of TrmB activity in cell extract from...
