Comparison of binding-affinity ranges and hydrolytic activities of various types of G proteins
| Type | Overall affinity for nucleotides | Kd(GTP) < Kd(GDP) | GTPase | Refs. |
|---|---|---|---|---|
| Ras-like | pM-nM | No | Slow | 21, 23 |
| Era, CgtA, FtsY | μM | No | Slow | 20, 32, 33, 35 |
| hGBP, MxA | μM | Yes | Fast | 13, 34 |
| NFeoB | μM | Yes | Slow | This work |
