Table 3 Xylose reductase (XR) and xylitol dehydrogenase (XDH) activity (U.mg protein- 1) of crude protein extracts from cells grown in defined medium with 20 g L-1 glucose

From: Improved xylose and arabinose utilization by an industrial recombinant Saccharomyces cerevisiae strain using evolutionary engineering

TMB 3400 0.09 ± 0.00 (*) 0.59 ± 0.08 (*)
TMB3061 0.13 ± 0.01 (*) 0.52 ± 0.03 (*)

  2. TMB3400 only harbours the heterologous xylose-utilizing pathway; TMB3063 is a derivative from TMB3061 (that contains the xylose and arabinose pathways) with extra-copies of AraA gene; TMB3130 is evolved from TMB3061.
