Directed Evolution of Propionyl-CoA Carboxylase for Succinate Biosynthesis

Trends Biotechnol. 2021 Apr;39(4):330-331. doi: 10.1016/j.tibtech.2021.02.006. Epub 2021 Feb 22.

Abstract

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.
