| cysM1 | pepN | stu0366 | stu1007 | Cysteine synthase; Belongs to the cysteine synthase/cystathionine beta- synthase family. | Lysyl-aminopeptidase, aminopeptidase N. | 0.813 |
| glyA | pepN | stu0755 | stu1007 | 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. | Lysyl-aminopeptidase, aminopeptidase N. | 0.848 |
