A dual effect of Ca2+ on chloroplast fructose-1,6-bisphosphatase
Chloroplast fructose-1,6-bisphosphatase, isolated from spinach leaves, was activated by preincubation with Ca2+ (or Mn2+), fructose-1,6-bisphosphate and dithiothreitol-reduced thioredoxin-f. Upon activation, the enzyme displayed high activity when measured at low concentrations of both fructose-1,6-...
