The present invention relates to a microorganism of the genus Cupriavidus or Ralstonia, which is genetically modified to express phosphomannose isomerase (EC5.3.1.8) and facilitated diffusion protein for mannose uptake (EC1.3.1.74), and optionally mannofructokinase (EC2.7.1.4) and/or xylose isomerase (EC 5.3.1.5), xylulokinase (E 2.7.1.17) and xylose proton symporter E or a high affinity ABC- transporter. A modified Cupriavidus or Ralstonia host is capable of growing on mannose, xylose, arabinose, glucose, or galactose, or a combination thereof as the carbon source.
本发明涉及一种经转基因表达磷酸甘露糖异构酶(EC5.3.1.8)和甘露糖摄取促进扩散蛋白(EC1.3.1.74)、甘露糖激酶(EC2.7.1.4)和/或木糖异构酶(EC 5.3.1.5)、木糖激酶(E 2.7.1.17)和木糖质子合流酶 E 或高亲和性 ABC 转运体。改良的铜绿菌或拉氏菌宿主能够以甘露糖、木糖、阿拉伯糖、葡萄糖或半乳糖或它们的组合作为碳源生长。
