SCHEDULED MAINTENANCE
Evolution inspired engineering of antibiotic biosynthesis enzymes
Chimeragenesis is an effective tool to probe the structure/function relationships of proteins without high-throughput screening systems. Here the proof-of-principle is presented with three pairs of proteins.
Immobilized enzymes: understanding enzyme – surface interactions at the molecular level
Interactions between immobilized enzymes and supporting surfaces are complex and context-dependent and can significantly alter enzyme structure, stability and activity.
A decade of DNA-hybrid catalysis: from innovation to comprehension
Since the pioneering work of Roelfes and Feringa in the field of DNA-based asymmetric catalysis, the unique chirality of oligonucleotides has allowed the development of a variety of asymmetric synthetic transformations. This review offers a complete overview of the field.
Aerobic catalytic systems inspired by copper amine oxidases: recent developments and synthetic applications
Recently, chemists have developed aerobic quinone-based catalytic systems in order to reproduce enzymatic activity and selectivity of copper amine oxidases but also to expand the scope of amine substrates.
Spatial organization of multi-enzyme biocatalytic cascades
Multi-enzyme cascades provide a wealth of valuable chemicals. Efficiency of reaction schemes can be improved by spatial organization of biocatalysts. This review will highlight various methods of spatial organization of biocatalysts: fusion, immobilization, scaffolding and encapsulation.
Post-translational modifications involved in the biosynthesis of thiopeptide antibiotics
Thiopeptide antibiotics are generated from ribosomally synthesized peptides via a cascade of post-translational modifications (PTMs).
Is more better? A comparison of tri- and tetrapeptidic catalysts
From an enzymatic perspective, there is a general notion that the bigger and more complex a catalytically active peptide is the more enzyme-like and the better it should become. But is this really true?
Novel chemoenzymatic oxidation of amines into oximes based on hydrolase-catalysed peracid formation
The efficient transformation of benzylamines into the corresponding oximes has been described by means of a chemoenzymatic process.

Structural insights into the ene-reductase synthesis of profens
New insight into the general utility of ene reductases for the synthesis of profens is established using structural and biocatalytic approaches.

Exploring the reversal of enantioselectivity on a zinc-dependent alcohol dehydrogenase
Alcohol Dehydrogenase (ADH) enzymes catalyse the reversible reduction of prochiral ketones to the corresponding alcohols.
A carbonyl reductase from Candida parapsilosis ATCC 7330: substrate selectivity and enantiospecificity
A purified carbonyl reductase (SRED) asymmetrically reduces ketones and α-ketoesters to (S)-alcohols with a potential application in the synthesis of industrially important chiral molecules.
Improving target amino acid selectivity in a permissive aminoacyl tRNA synthetase through counter-selection
We report the selection and characterization of an improved acridon-2-ylalanine aminoacyl tRNA synthetase.
Multidrug resistance regulators (MDRs) as scaffolds for the design of artificial metalloenzymes
Artificial metalloenzymes were created from multidrug resistance regulator proteins by in vivo incorporation of an unnatural metal binding amino acid.
Inter- and intramolecular aldol reactions promiscuously catalyzed by a proline-based tautomerase
The enzyme 4-oxalocrotonate tautomerase, which has a catalytic amino-terminal proline, was shown to promiscuously catalyze inter- and intramolecular aldol reactions.
Converting Pasteurella multocida α2–3-sialyltransferase 1 (PmST1) to a regioselective α2–6-sialyltransferase by saturation mutagenesis and regioselective screening
A sialyltransferase mutant for selectively α2–6-sialylating terminal galactose in polyLacNAc-glycan was identified using a novel microtiter plate-based screening assay.
Constrained evolution of a bispecific enzyme: lessons for biocatalyst design
Analysis of the natural evolution of bispecificity in triazine hydrolase highlights the importance of epistasis in protein engineering and evolution.
