Schematic diagram illustrating the roles of FMT (methionyl formylation) and the two redundant PDF enzymes (polypeptide deformylation) during bacterial translation (DefA and DefB). The dashed line indicates the use of unmodified Met-tRNAfMet in initiation in the FMT bypass mutant strains. Note that some polypeptides are considered mature in the absence of removal of the initiating Met residue (dotted line).
