| Cbs | RN09_2611 | RN09_1336 | RN09_2611 | Cystathionine beta-synthase. | Methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate. | 0.534 |
| Cbs | ThrA | RN09_1336 | RN09_1599 | Cystathionine beta-synthase. | Homoserine dehydrogenase; Overlaps another CDS with the same product name. | 0.824 |
| Cbs | glyA | RN09_1336 | RN09_0088 | Cystathionine beta-synthase. | 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. | 0.930 |
| Cbs | metXA | RN09_1336 | RN09_4064 | Cystathionine beta-synthase. | Homoserine O-acetyltransferase; Transfers an acetyl group from acetyl-CoA to L-homoserine, forming acetyl-L-homoserine. | 0.838 |
| Cbs | metZ | RN09_1336 | RN09_0479 | Cystathionine beta-synthase. | O-succinylhomoserine sulfhydrylase; Catalyzes the formation of L-homocysteine from O-succinyl-L- homoserine (OSHS) and hydrogen sulfide. | 0.988 |
| Cbs | thrB | RN09_1336 | RN09_1602 | Cystathionine beta-synthase. | Homoserine kinase; Catalyzes the ATP-dependent phosphorylation of L-homoserine to L-homoserine phosphate; Belongs to the GHMP kinase family. Homoserine kinase subfamily. | 0.814 |
