General Information
| General Information | Comment | Organism |
|---|---|---|
| physiological function | growth rate of a subunit GrdA gene deletion strains is similar to that of the wild-type. Intracellular proline concentrations depend on the activity of proline reductase but not on the activity of glycine reductase. Subunit grdE levels in in a subunit GrdA mutant are 10fold higher than in wild-type cells and12fold more abundant in glycine-supplemented medium. Induction of grdE expression in the presence of glycine is notably higher in the grdA mutant than in the wild-type strain | Clostridioides difficile |
