Description

Methionyl-tRNA formyltransferase (FMT) (EC:2.1.2.9) transfers a formyl group onto the amino terminus of the acyl moiety of the methionyl aminoacyl-tRNA. The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and by impairing its binding to EFTU-GTP. This family also includes formyltetrahydrofolate dehydrogenases, which produce formate from formyl-tetrahydrofolate. These enzymes contain an N-terminal domain in common with other formyl transferase enzymes (IPR002376). The C-terminal domain has an open beta-barrel fold [PMID: 8887566].

The C-terminal domain of FMT structurally resembles methylpurine-DNA glycosylases (MPG). Human 3-methyladenine DNA glycosylase (AAG) catalyses the first step of base excision repair by cleaving damaged bases from DNA, excising a chemically diverse selection of substrate bases damaged by alkylation or deamination [PMID: 11106395].
