| 2.7.4.1 | Cs+ |
activates wild-type, full-length enzyme paPpx(1-506) |
756630 |
| 2.7.4.1 | K+ |
a nonessential activator of paPpx, presence of K+ does not affect the affinity of the enzyme for Mg2+, activates wild-type, full-length enzyme paPpx(1-506). The activity curve obtained with K+ is sigmoid and reaches its maximum activity at concentrations of 80 mM. Km(app)K+ is 42 mM |
