Recent developments in pyridine nucleotide regeneration.

Cofactor regeneration by a soluble pyridine nucleotide transhydrogenase for biological production of hydromorphone.

We have applied the soluble pyridine nucleotide transhydrogenase of Pseudomonas fluorescens to a cell-free system for the regeneration of the nicotinamide cofactors NAD and NADP in the biological production of the important semisynthetic opiate drug hydromorphone. The original recombinant whole-cell system suffered from cofactor depletion resulting from the action of an NADP(+)-dependent morphi...

Biological Production of Hydromorphone Pyridine Nucleotide Transhydrogenase for Cofactor Regeneration by a Soluble

A Novel Whole-Cell Biocatalyst with NAD+ Regeneration for Production of Chiral Chemicals

BACKGROUND The high costs of pyridine nucleotide cofactors have limited the applications of NAD(P)-dependent oxidoreductases on an industrial scale. Although NAD(P)H regeneration systems have been widely studied, NAD(P)(+) regeneration, which is required in reactions where the oxidized form of the cofactor is used, has been less well explored, particularly in whole-cell biocatalytic processes. ...

Nanosized biomaterials for regenerative medicine

This review discusses recent developments in the field of nanosized biomaterials and their use in tissue regeneration approaches. The aim is to provide an overview of the research focused on nanoparticle-based strategies to stimulate regeneration. In particular, nanoparticles improve the regenerative capabilities of biomaterials offering ways to control surface and mechanical properties. Moreov...
