PYROPHOSPHATE-DEPENDENT PHOSPHOFRUCTO-1-KINASE COMPLEMENTS FRUCTOSE 1,6-BISPHOSPHATASE BUT NOT PHOSPHOFRUCTOKINASE DEFICIENCY IN ESCHERICHIA-COLI

The gene from Propionibacterium freudenreichii for PP(i)-dependent pho sphofructo-1-kinase, an enzyme that is found in some bacteria, in a nu mber of anaerobic protists, and in plants, complements the absence of fructose 1,6-bisphosphatase in Escherichia coli but does not complemen t the deficiency of the ATP-dependent phosphofructokinase.
