MetaCyc Enzyme: cytosolic fructose-bisphosphate aldolase

Species: Zea mays

A cytosolic enzyme with fructose-1,6-bisphosphate aldolase activity was isolated from the leaves of well developed corn (Zea mays L. Inrafrueh) plants [Schnarrenberger86]. This enzyme was separated from its plastidic homolog isolated simultaneously (see chloroplastic fructose-bisphosphate aldolase). In addition to fructose 1,6-bisphosphate, the enzyme was shown to catalyze the aldol cleavage of β-D-fructofuranose 1-phosphate. The cytosolic enzyme represented 4.5% of the total leaf aldolase activity. Additionally, this cytosol aldolase was shown to have a Km (F1,6P) value 5 times smaller than that of the chloroplast aldolase. However, the Km (F1P) values for either enzymes are relatively similar [Schnarrenberger86].
