WebJan 16, 2013 · Background. Bacterial protein biosynthesis usually depends on a formylated methionyl start tRNA but Staphylococcus aureus is viable in the absence of Fmt, the tRNA Met formyl transferase. fmt mutants exhibit reduced growth rates indicating that the function of certain proteins depends on formylated N-termini but it has remained unclear, which …
WebProtein synthesis involves two methionine-isoaccepting tRNAs, an initiator and an elongator. In eubacteria, mitochondria, and chloroplasts, the addition of a formyl group gives its full functional identity to initiator Met …
WebThe formation of tRNA-bound fMet is catalyzed by the mitochondrial methionyl-tRNA formyltransferase (MTFMT), which requires 10-formyl tetrahydrofolate (THF) as a formyl donor. 10-Formyl-THF is a byproduct of the folate cycle and one-carbon metabolism. ...
