Post-Translational Modifications (PTM’s)

Protein synthesis occurs during a process called translation. Most proteins undergo some modification before undertaking any function assigned to them. Post-translational modification (PTM) of proteins refers to these covalent chemical modifications, protein may undergo after translation. This poses a much bigger phenomena when it comes to the synthetic production of these proteins. Chemical reagents undergo certain processes that are a part of fixed manufacturing systems. Many of which are unable to adapt or disrupt in order to tailor to a PTM’s biochemical properties.

PTM’s have become a growing focus in protein and bioreagent production: As more complex and difficult-to-express proteins extend into the commercial market, the industry is facing bottlenecks and PTM obstacles to producing certain proteins of interest.


The biochemistry behind these modifications are not universally updated: This piece will help outline and review the top key PTM’s and their latest understandings with mechanics and chemistry.


Biomanufacturing solutions are crucial to counter these PTM obstacles: With proper understanding of the biochemistry, researchers will be more equipped to understand what to expect from the manufacturing end when scouting difficult proteins with key PTM’s.
