RS/tRNA Additional Notes
The E coli version functions ~400x less well with Aha than with Met, but good enough for Aha to be incorporated a 95% level in a Met E coli Met auxotroph.
In the case of HEK293 cells, one analysis indicated Aha incorporation in place of Met at about a 30% level.
Based on these studies, it may be that the Met RS from any species could also incorporate Aha into proteins.
