Specific enzyme activity of PrpC measured in crude extracts of R. eutropha H16. Cells were cultivated in MSM under storage conditions containing (i) 1% (w/v) sodium gluconate, (ii) 1% (w/v) sodium gluconate plus 1% (v/v) TDP, or (iii) DTDP. After 24, 48, 72, and 96 h of cultivation, cells were harvested, cell-free crude extracts were prepared, and the activity of 2-methylcitrate synthase was measured. Data were generated from two independent biological experiments resulting in mean values of six replicates
