Non-PTS uptake and subsequent metabolism of glucose in Pediococcus halophilus as demonstrated with a double mutant defective in phosphoenolpyruvate:mannose phosphotransferase system and in phosphofructokinase.

Abstract excerpt

Pediococcus halophilus possesses phosphoenolpyruvate:mannose phosphotransferase system (man:PTS) as a main glucose transporter. A man:PTS defective (man:PTSd) strain X-160 could, however, utilize glucose. A possible glucose-transport mechanism other than PTS was studied with the strain X-160 and its derivative, man:PTSd phosphofructokinase defective (PFK-) strain M-13. Glucose uptake by X-160 at pH 5.5 was...
