The genetic basis of 3-hydroxypropanoate metabolism in Cupriavidus necator H16

Background 3-Hydroxypropionic acid (3-HP) is a promising platform chemical with various industrial applications. Several metabolic routes to produce 3-HP from organic substrates such as sugars or glycerol have been implemented in yeast, enterobacterial species and other microorganisms. In this study, the native 3-HP metabolism of Cupriavidus necator was investigated and manipulated as it represents a promising chassis for the production of 3-HP and other fatty acid derivatives from CO2 and H2.
