Biocatalytic Friedel-Crafts alkylation using non-natural cofactors.
The formation of C C bonds is a central aspect of synthetic organic chemistry. However, in biocatalysis only few enzymes capable to perform this reaction are known, among which aldolases, transketolases, and hydroxynitril lyases have been investigated thoroughly. Some have even found their way into industrial applications. Friedel–Crafts alkylation is a classic organic reaction of great importa...
متن کاملSilica/PVA biocatalytic nanofibers
Bioencapsulation has been a promising technique for various biotechnological and medical applications. Nevertheless, when encapsulated, the activity of the encapsulated biologicals is usually reduced due to diffusional resistance and use of organic solvents in the process. Here, we developed a sol–gel electrospinning technique to encapsulate a bacterium, Escherichia coli expressing a biocatalys...
متن کاملBiocatalytic synthesis of vanillin.
The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was converted to the corresponding alcohol prod...
متن کاملBiocatalytic degradation of pollutants.
Microbial reactions play key roles in biocatalysis and biodegradation. The recent genome sequencing of environmentally relevant bacteria has revealed previously unsuspected metabolic potential that could be exploited for useful purposes. For example, oxygenases and other biodegradative enzymes are benign catalysts that can be used for the production of industrially useful compounds. In conjunct...
متن کاملBiocatalytic microcontact printing.
Immobilized biocatalytic lithography is presented as an application of soft lithography. In traditional microcontact printing, diffusion limits resolution of pattern transfer. By using an immobilized catalyst, the lateral resolution of microcontact printing would depend only on the length and flexibility of the tether (<2 nm) as opposed to diffusion (>100 nm). In the work, exonuclease reversibl...
