Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Chemoenzymatic Route toward a De Novo Enantioselective Total Synthesis of (S)‐Baclofen Based on Metal‐Catalyzed Hydroformylation and Enzymatic Transamination

ChemBioChem, EarlyView.
A unique chemoenzymatic synthesis route toward (S)‐baclofen is presented, which highlights a hydroformylation and biocatalysis step toward the synthesis of such a challenging β‐chiral amino acid. The shown methodology exhibits high conversions and enantiomeric excess and is transferable to other β‐chiral amines and amino acids.

Diversity of ThDP‐Dependent Enzymes Forming Chiral Tertiary Alcohols

ChemBioChem, EarlyView.
Chiral tertiary alcohols are widespread in nature and bioactive compounds; however, their asymmetric synthesis faces several challenges. This review outlines the toolbox of ThDP‐dependent enzymes able to produce tertiary alcohols through the formation of CC bond formation using ketones as acceptor substrates. Herein, the substrate scope, the diversity

Activity‐enhancing mutations in an LmrR‐based artificial metalloenzyme destabilize the protein scaffold and alter its conformational plasticity

ChemBioChem, Accepted Article.
Artificial metalloenzymes (ArM) hold great potential for the sustainable catalysis of complex new‐to‐nature reactions. To efficiently improve the catalytic efficacy of ArMs a rational approach is desirable, requiring detailed molecular insight into their conformational landscape.

Mammalian Tolerance to Amino Acid Heterochirality

ChemBioChem, EarlyView.
Organisms preferentially use l‐amino acids (l‐AAs). However, de novo synthesized l‐AAs are in part converted to d‐AAs. The ribosome has a robust system to use l‐AAs for protein synthesis, whereas non‐ribosomal synthesis can also use d‐AAs. Furthermore, some AA residues can be post‐translationally isomerized through enzymatic or spontaneous processes ...
