Fig. 1From: Effects of CO2 limitation on the metabolism of Pseudoclostridium thermosuccinogenesMetabolic pathways from phosphoenolpyruvate (PEP) to the different fermentation products in P. thermosuccinogenes. The dashed grey arrow represents the glycolysis, which relies on a PPi-dependent phosphofructokinase. The green arrows represent the malate shunt for the conversion of PEP to pyruvate. ACDH, acetaldehyde dehydrogenase; ACN, aconitase; ACS, acetyl-CoA synthetase; ADH, alcohol dehydrogenase; AK, acetate kinase; CS, citrate synthase; Flx-Hdr, NADH dehydrogenase/heterodisulfide reductase bifurcation complex; FH, fumarate hydratase; FR, fumarate reductase; ICD, isocitrate dehydrogenase; LDHL, l-lactate dehydrogenase; MDH, malate dehydrogenase; ME, malic enzyme; OOR, 2-oxoglutarate:ferredoxin oxidoreductase; PEPCK, phosphoenolpyruvate carboxykinase; PFL, pyruvate formate lyase; PFOR, pyruvate:ferredoxin oxidoreductase; PPdK, pyruvate, phosphate dikinase; PTA, phosphate acetyltransferase; PYK, pyruvate kinase.
