A special fructose bisphosphate functions as a cytoplasmic regulatory metabolite in green leaves.

Abstract

Fructose 2,6-bisphosphate (Fru-2,6-P(2)), a regulatory metabolite discovered in animal cells and recently reported to occur in etiolated seedlings, was found to be present in the cytoplasmic fraction of leaves of spinach and peas (typical C(3) plants, in which a three-carbon carboxylic acid is a major early photosynthetic product). At concentrations… (More)
