Figure 1From: An insight into the role of phosphotransacetylase (pta) and the acetate/acetyl-CoA node in Escherichia coliSimplified model for the central metabolic network of E. coli metabolism. The enzymes involved (and their codifying genes) are shown in the figure, ACEK (aceK), isocitrate dehydrogenase phosphatase/kinase; ACK (ackA), acetate kinase; ACS (acs), acetyl-CoA synthetase; ICDH (icd), isocitrate dehydrogenase; ICL (aceA), isocitrate lyase; ICLR (iclR), repressor of the glyoxylate shunt; MDH (maeB), malate dehydrogenase; ME (sfcA), malic enzyme, PFL (pfl) pyruvate:formate lyase; PTA (pta), phosphotransacetylase (Ecocyc-Metacyc [45]).Back to article page
