Methionyl-tRNA formyltransferase, N-terminal hydrolase domain; Methionyl-tRNA formyltransferase (Met-tRNA-FMT), N-terminal formyltransferase domain. Met-tRNA-FMT transfers a formyl group from N-10 formyltetrahydrofolate to the amino terminal end of a methionyl-aminoacyl-tRNA acyl moiety, yielding formyl-Met-tRNA. Formyl-Met-tRNA plays essential role in protein translation initiation by forming complex with IF2. The formyl group plays 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.

10-formyltetrahydrofolate dehydrogenase (FDH), N-terminal hydrolase domain; This family represents the N-terminal hydrolase domain of the bifunctional protein 10-formyltetrahydrofolate dehydrogenase (FDH). This domain contains a 10-formyl-tetrahydrofolate (10-formyl-THF) binding site and shares sequence homology and structural topology with other enzymes utilizing this substrate. This domain functions as a hydrolase, catalyzing the conversion of 10-formyl-THF, a precursor for nucleotide biosynthesis, to tetrahydrofolate (THF). The overall FDH reaction mechanism is a coupling of two sequential reactions, a hydrolase and a formyl dehydrogenase, bridged by a substrate transfer step. The N-terminal hydrolase domain removes the formyl group from 10-formyl-THF and the C-terminal NADP-dependent dehydrogenase domain then reduces the formyl group to carbon dioxide. The two catalytic domains are connected by a third intermediate linker domain that transfers the formyl group, covalently attached to the sulfhydryl group of the phosphopantetheine arm, from the N-terminal domain to the C-terminal domain.

HypX protein, N-terminal hydrolase domain; The family represents the N-terminal hydrolase domain of HypX protein. HypX is involved in the maturation process of active [NiFe] hydrogenase. [NiFe] hydrogenases function in H2 metabolism in a variety of microorganisms, enabling them to use H2 as a source of reducing equivalent under aerobic and anaerobic conditions. [NiFe] hydrogenases consist of a large and a small subunit. The large subunit contains [NiFe] active site, which is synthesized as a precursor without the [NiFe] active site. This precursor then undergoes a complex post-translational maturation process that requires the presence of a number of accessory proteins. HypX has been shown to be involved in this maturation process and have been proposed to participate in the generation and transport of the CO and CN ligands. However, HypX is not present in all hydrogen-metabolizing bacteria. Furthermore, hypX deletion mutants have a reduced but detectable level of hydrogenase activity. Thus, HypX might not be a determining factor in the matur ation process. Members of this group have an N-terminal formyl transferase domain and a C-terminal enoyl-CoA hydratase/isomerase domain.

Carboxy-terminal domain of Formyltransferase and similar domains; This family represents the C-terminal domain of formyltransferase and similar proteins. This domain is found in a variety of enzymes with formyl transferase and alkyladenine DNA glycosylase activities. The proteins with formyltransferase function include methionyl-tRNA formyltransferase, ArnA, 10-formyltetrahydrofolate dehydrogenase and HypX proteins. Although most proteins with formyl transferase activity contain this C-terminal domain, prokaryotic glycinamide ribonucleotide transformylase (GART), a single domain protein, only contains the core catalytic domain. Thus, the C-terminal domain is not required for formyl transferase catalytic activity and may be involved in substrate binding. Some members of this family have shown nucleic acid binding capacity. The C-terminal domain of methionyl-tRNA formyltransferase is involved in tRNA binding. Alkyladenine DNA glycosylase is a distant member of this family with very low sequence similarity to other members. It catalyzes the first step in base excision repair (BER) by cleaving damaged DNA bases within double-stranded DNA to produce an abasic site and shows ability to bind to DNA.
