| Functional Family | 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase |
Enzyme Information
| 2.1.1.14 |
5-methyltetrahydropteroyltriglutamate--homocysteine S-methyltransferase.
based on mapping to UniProt O50008
5-methyltetrahydropteroyltri-L-glutamate + L-homocysteine = tetrahydropteroyltri-L-glutamate + L-methionine.
-!- Requires phosphate. -!- The enzyme from Escherichia coli also requires a reducing system. -!- Unlike EC 2.1.1.13 this enzyme does not contain cobalamin.
