Glycine decarboxylase; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family.

Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

Dihydrolipoamide dehydrogenase; Similar to GI|1073212 (percent identity: 57 %/query alignment coverage: 100.2 %/subject alignment coverage: 101.7 %); identified by sequence similarity; putative; ORF located using Glimmer/RBSfinder.

Bifunctional methylenetetrahydrofolate dehydrogenase/methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.

Dihydrolipoamide dehydrogenase; Similar to SP|P14218 (percent identity: 58 %/query alignment coverage: 97.6 %/subject alignment coverage: 100.0 %); identified by sequence similarity; putative; ORF located using Glimmer/RBSfinder.

Bifunctional purine biosynthesis protein; Similar to SP|P15639 (percent identity: 59 %/query alignment coverage: 91.3 %/subject alignment coverage: 99.1 %); identified by sequence similarity; putative; ORF located using Glimmer/RBSfinder.

5,10-methylenetetrahydrofolate reductase; Similar to SP|O67422 (percent identity: 37 %/query alignment coverage: 99.6 %/subject alignment coverage: 92.6 %); identified by sequence similarity; putative; ORF located using Glimmer/RBSfinder; Belongs to the methylenetetrahydrofolate reductase family.

5'-phosphoribosylglycinamide transformylase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.

methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
