Table 2. Effect of metal ions on the activity of KB-SP.

Metal ion	Relative activity/%
Control KCl CaCl₂ CuCl₂ ZnCl₂ MgCl₂	(100)^b (129.8±2.7)^a (121.5±5.5)^a (19.7±0.6)^c (2.9±1.6)^d (124.5±2.7)^a

c(metal ion)=10 mM. Mean values±standard error with different superscript are significantly different (p≤0.05)
