Initiation of protein synthesis has been studied in the presence of the tetrahydrofolic acid analogues trimethoprim or aminopterin in Bacillus subtilis. This bacterium can grow in the presence of the inhibitors, when the medium is supplemented with the low molecular weight products of tetrahydrofolate-dependent pathways. In an attempt to show whether formylation of initiator tRNA is a prerequisite for the iniation of protein synthesis in procaryotic cells, the amount of N-formylmethionine in tRNA and in protein has been determined. The level of formylation of methionyl-tRNA was found to be 70% in control cells and approximately 2% in inhibitor-treated cells. The content of formyl groups in protein has also been found to be drastically reduced. Trimethoprim or aminopterin did not alter the amount of tRNAMet nor the degree of aminoacylation of tRNAMet in vivo. These results indicate that in B. subtilis inititation of protein synthesis is possible without prior formylation of initiator tRNA.
