| CysE | GlnS | PTH_0294 | PTH_0293 | Serine acetyltransferase. | Glutamyl- and glutaminyl-tRNA synthetases; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu). | 0.824 |
| CysE | GlyA | PTH_0294 | PTH_2824 | Serine acetyltransferase. | Glycine/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. | 0.857 |
