DOI: 10.1038/s41598-019-53177-3
Abstract: One of the main factors hampering the implementation in industry of transaminase-based processes for the synthesis of enantiopure amines is their often low storage and operational stability. Our still limited understanding of the inactivation processes… read more here.
