Putative tRNA-binding sites. (A) Methyl transfer activity of the alanine-substituted mutant proteins. The mutant name indicates the site of alanine substitution. The initial velocity of WT TkoTrm11 is expressed as 100%. Error-bar indicates the standard deviation (SD) that was calculated between three independent experiments. (B) The binding-affinity values of the WT TkoTrm11 and K151A mutant for Tko tRNATrp were analyzed by a gel mobility shift assay. (C) The binding-affinity values of WT TkoTrm11 and R152A mutant for Tko tRNATrp were also analyzed by a gel mobility shift assay. (D) The binding-affinity values of WT TkoTrm11 and R152A mutant for Tko tRNATrp were analyzed by a gel mobility shift assay. The formations of a complex by WT TkoTrm11 or each of the three mutants with Tko tRNATrp and unbound free tRNA were indicated by two black lines labeled on the right side of the gel.
