Regulation of the activation of chloroplast fructose-1,6-bisphosphatase: Inhibition by spermidine and spermine
The activation of chloroplast fructose-1,6-bisphosphatase by fructose-1,6-bisphosphate, Ca2+, DTT and chloroplast thioredoxin-f is prevented by either spermidine or spermine; on the contrary, other amino compounds do not replace polyamines in this reversible effect. On the other hand, neither spermi...
