Journal ArticleDOI

Opportunities and challenges for combining chemo- and biocatalysis

TL;DR: This Review focuses on efforts to combine chemo- and biocatalysts, outlining the opportunities achievable by this approach and also efforts to overcome any incompatibilities between these different systems.
Journal ArticleDOI

Identification of (S)-selective transaminases for the asymmetric synthesis of bulky chiral amines

TL;DR: The creation of highly active and stereoselective transaminases starting from fold class I are reported and can be engineered into other protein scaffolds with sequence identities as low as 70%, and should have a broad impact in the field of biocatalytic synthesis and enzyme engineering.
Journal ArticleDOI

Benzoylformate Decarboxylase from Pseudomonas putida as Stable Catalyst for the Synthesis of Chiral 2‐Hydroxy Ketones

TL;DR: A new enzyme tool comprising a vast applicability for stereoselective synthesis and a simple way to increase the enantiomeric excess of (S)-2-hydroxy-1-phenyl-propanone from 90% to 95% by skillful choice of the reaction parameters is presented.
Journal ArticleDOI

Exchanging the substrate specificities of pyruvate decarboxylase from Zymomonas mobilis and benzoylformate decarboxylase from Pseudomonas putida.

TL;DR: Comparison of the X-ray structures of both enzymes identified two residues in each that were likely to be involved in determining substrate specificity that proved to be a real chimera between PDC and BFD and provided the most interesting result with an almost complete reversal of the stereochemistry of its 2-hydroxypropiophenone product.
Journal ArticleDOI

The synthetic development of the anti-influenza neuraminidase inhibitor oseltamivir phosphate (Tamiflu®): A challenge for synthesis & process research

TL;DR: The evolution of the synthesis of oseltamivir phosphate (Tamiflu®) used for the oral treatment and prevention of influenza virus infections (viral flu) is described in this article.
