   2.7.7.48 | Ca2+ |
divalent cation required, Ca2+ shows about 20% of the activity with Mg2+ at about 1 mM |
643395 |
| 2.7.7.48 | K+ |
K+ exhibits a stimulatory effect at 25 mM, while the stimulatory effect decreases when the concentration of K+ is higher than 25 mM |
672810 |
| 2.7.7.48 | K+ |
KCl, activity is increased by a factor of about 1.2-1.5 when the final salt concentration is raised to 60 mM by the addition of NaCl, KCl or NH4Cl |
