| additional information | - |
at pH 8.45 the transferase activity of glutamine synthetase is independent of the state of adenylylation, whereas at pH 7.15, the activity depends on the amount of enzyme present and the state of adenylylation | Pseudomonas fluorescens |
| additional information | - |
at pH 8.75 the transferase activity of glutamine synthetase is independent of the state of adenylylation, whereas at pH 7.4, the activity depends on the amount of enzyme present and the state of adenylylation | Pseudomonas aeruginosa |
