Engineered Enzyme Boosts Asymmetric Synthesis
Researchers optimized a Bacillus megaterium enzyme to catalyze bulky precursors for chemical manufacturing.
Updated on Oct. 14, 2026 in Chemistry
Researchers have engineered a 13M omega-transaminase variant from Bacillus megaterium that demonstrates catalytic activity 106 times higher than the wild type. This research-stage development enables the asymmetric synthesis of ABP with greater than 99% enantiomeric excess.
Why it matters
This development overcomes long-standing limitations in omega-transaminase utility, specifically the inability to accommodate bulky ketone precursors. It expands the industrial potential for sustainable, high-precision chemical manufacturing.
The 13M variant provides a 106-fold catalytic improvement over the natural enzyme and maintains a greater than 99% enantiomeric excess. This precision allows for the reliable synthesis of ABP molecules which were previously inaccessible.
The players
Bacillus megaterium
A soil-dwelling bacterium that serves as the biological source for the engineered omega-transaminase enzyme.
The details
Researchers utilized Funnel metadynamics — a computational technique to simulate how molecules fold and bind — alongside PathDetect-SOM and path collective variables to map the free energy surface of substrate binding. These tools, paired with dynamic cross-correlation network analysis, allowed the team to identify distal regulatory sites—locations on the protein far from the active site that control how it functions—governing bottleneck regions of the reaction process.

The Tech Race
This research follows a broader trend of optimizing biocatalysts to replace traditional, metal-based chemical synthesis methods. By enabling the transformation of bulky ketone precursors, this work closes a specific performance gap in current industrial enzyme portfolios.
This research is currently at the laboratory stage and does not impact commercial workflows or chemical availability today. Future industrial adoption depends on demonstrating stability and yield in high-volume, multi-liter reaction environments.
The takeaway
The engineering of the 13M variant marks a shift in how computational tools can unlock previously recalcitrant enzymatic reactions. Watch for future benchmarks evaluating this variant's performance in pilot-scale manufacturing trials.
