N "-Formyltetrahydrofolic synthetase

The initiator tRNA molecule in prokaryotes—tRNA — has several properties that distinguish it from all other tRNA molecules. One feature is that the tRNA is first acylated with methionine, and then the methionine is modified. Acylation is by methionyl tRNA synthetase, which also charges tRNA . However, the methionine of charged tRNA is immediately recognized by another enzyme, tRNA methionyl transformylase, which transfers a formyl group from N °-formyltetrahydrofolate (fTHF) to the amino group of the methionine to form... [Pg.574]

N -Formyltetrahydrofolate is formed by the condensation of THFA with formate in the presence of ATP. Formyltetrahydrofolate synthetase has been found in bacteria and in mammalian tissues. The erythrocyte enzyme has been partially purified. [Pg.294]
