Genomic SELEX screening predicted a number of novel target genes, including yggF, to be under the control of transcriptional activator cAMP-CRP. The data suggested that CRP has a major role in control of the switch between glycolysis and gluconeogenesis [Shimada11a]. Genomic SELEX screening is described in [Gold95].

Enzymatic reaction of: fructose-1,6-bisphosphatase
EC Number: 220.127.116.11
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
The reaction is physiologically favored in the direction shown.
In Pathways: photosynthetic 3-hydroxybutanoate biosynthesis (engineered) , superpathway of hexitol degradation (bacteria) , superpathway of N-acetylneuraminate degradation , superpathway of glycolysis and Entner-Doudoroff , superpathway of glycolysis, pyruvate dehydrogenase, TCA, and glyoxylate bypass , gluconeogenesis I , glycolysis II (from fructose 6-phosphate) , glycolysis I (from glucose 6-phosphate)
Substrate binding shows positive cooperativity, with a Hill coefficient of ~2.0 [Brown09].
The enzyme had low activity toward glucose 1,6-bisphosphate. Non-substrates included ribulose 1,5-bisphosphate, fructose 2,6-bisphosphate, and fructose 1-phosphate. Of several divalent ions tested, only Mn2+ served as cofactor [Brown09].
Addition of 1 mM dithiothreitol increased the activity 40-50%, whereas 1 mM ATP reduced the activity by 40%. Addition of 1 mM AMP, ADP, PEP, and glycerol 3-phosphate had no significant effect on activity [Brown09].
pH(opt): 7.5-8 [Brown09]
