Fig. 6From: Proteomic and biochemical responses to different concentrations of CO2 suggest the existence of multiple carbon metabolism strategies in Phaeodactylum tricornutumActivities of PYR metabolism-, TCA cycle- and glycolysis-related enzymes in different CO2-measured P. tricornutum. A–F Display the enzyme activity of PK, PYC, PDH, PDC, CS, and GAPDH, respectively. Data are expressed as means ± SD of three replicates. PK: pyruvate kinase; PYC: pyruvate carboxylase; PDH: pyruvate dehydrogenase complex; PDC: pyruvate decarboxylase; CS:citrate synthase; GAPDH: glyceraldehyde 3-phosphate dehydrogenase; NC: normal CO2; LC: low CO2; HC: high CO2Back to article page
