Due to low carboxylase activity, CO2 biotransformation is challenging to achieve using natural CO2 fixation pathways. Liu et al. have improved the activity of propionyl-CoA carboxylase (PCC) 94-fold, enabling the efficient synthesis of succinate from acetyl-CoA and paving the way for CO2 assimilation via the 3-hydroxypropionate (3-HP) bicycle or 3-hydroxypropionate/4-hydroxybutyrate (3-HP/4-HB) cycle.
