Table 2 Effects of metal ions on the activity of mAP

From: A novel psychrophilic alkaline phosphatase from the metagenome of tidal flat sediments

Metal ions (1 mM) % AP activity restored*
None 0.11
Ca2+ 45.6
Co2+ 27.3
Zn2+ 12.8
Ni2+ 1.66
Mn2+ 1.44
Mg2+ 0.81
Cu2+ 0.24
  1. *Results are expressed as the percentage of activity restored when compared with the enzyme that was not dialyzed against 5 mM EDTA (see Methods). All results are the means of three experiments wherein variation was less than 10%.
