Abstract: | Fructose 2,6-bisphosphate inhibits phosphoglucomutase. The inhibition is mixed with respect to glucose 1,6-bisphosphate and non-competitive with respect to glucose 1-phosphate. In contrast with fructose 1,6-bisphosphate and glycerate 1,3-bisphosphate, which also possess inhibitory effect, fructose 2,6-bisphosphate does not phosphorylate phosphoglucomutase. Fructose 2,6-bisphosphate preparations contain contaminants which can explain artefactual results previously reported. |
