Cloning, expression, and sequence of an allosteric mutant ADPglucose pyrophosphorylase from Escherichia coli B.

Archives of biochemistry and biophysics - 1 Apr 1993

Meyer C R, Ghosh P, Nadler S, Preiss J

Abstract excerpt

Escherichia coli B mutant strain SG14 accumulates glycogen at 28% of the rate observed for the parent strain. This is due to the presence of an ADPglucose pyrophosphorylase with altered allosteric properties including lower apparent affinities for substrates, the activator, fructose-1,6-bisphosphate, and the inhibitor, AMP. The mutant enzyme also is completely insensitive to activation by NADPH. To clone this...
