Abstract:

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-bisphosphate and Mg2+. On the contrary, the activity of chloroplast fructose-1,6-bisphosphatase was inhibited by Ca2+. These results suggest that Ca2+ (or Mn2+) is potentially important in the regulation of the chloroplast fructose-1,6-bisphosphatase reaction (activation and catalysis). © 1980, Academic Press, Inc..
