| agaS | lacD | spr0064 | spr1073 | Tagatose-6-phosphate ketose/aldose isomerase. | Tagatose 1,6-diphosphate aldolase; Belongs to the aldolase LacD family. | 0.766 |
| agaS | pfkA | spr0064 | spr0796 | Tagatose-6-phosphate ketose/aldose isomerase. | 6-phosphofructokinase I; Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis. | 0.904 |
| glyA | lacB | spr0928 | spr1075 | 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. | Galactose-6-phosphate isomerase LacB subunit. | 0.920 |
