متن کاملImprovement of amorpha-4,11-diene production by a yeast-conform variant of Vitreoscilla hemoglobin.
Amorpha-4,11-diene is the precursor of the antimalarial compound artemisinin. The effect of Vitreoscilla hemoglobin (VHb) and its yeast-conform variant (VHbm) on amorpha-4,11-diene production in engineered Saccharomyces cerevisiae was investigated. First, the VHb gene was mutated to the yeast-conform variant VHbm based on step-by-step extension of a short region of the gene through a series of ...
