Collaboration with Merck published in Science magazine

REDWOOD CITY, Calif., June 17, 2022 (GLOBE NEWSWIRE) — Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company enabling the promise of synthetic biology, today announces publication with Merck, known as MSD’s name outside of the United States and Canada, from an article in the peer-reviewed journal Sciencedetailing the development of a suite of enzymes and their application for the site-selective synthesis of insulin bioconjugates.

“Our ongoing agreement with Merck has produced multiple scientific breakthroughs in the field of enzyme engineering. This work described in Science is another great example of how scientific collaboration can effectively address the challenges facing the biotech industry,” said John Nicols, President and CEO of Codexis. “The development of this enzyme toolkit opens up opportunities to generate new clinical leads that were not possible before.”

The publication describes enzyme development and optimization using Codexis’ proprietary CodeEvolver® technology platform. Each enzyme has a unique specificity and has been evaluated for its ability to modify insulin. The work described highlights how enzymes can be engineered to functionalize peptides in targeted ways beyond what is possible with conventional chemical approaches.

“The ability to specifically target chemical moieties along a peptide chain opens up many possibilities for future protein modification,” said Ania Fryszkowska, Ph.D., Director, Biocatalysis, Enabling Technologies, Merck Research Laboratories and an author correspondent of the publication.
