Enzymatic synthesis of galacto-oligosaccharides is usually performed at high initial substrate concentrations since higher yields are obtained. We report here on the stability of β-galactosidase from Bacillus circulans at 25, 40, and 60°C in buffer, and in systems with initially

Exposure of dark-grown (etiolated) seedlings to light induces the heterotrophic-to-photoautotrophic transition (de-etiolation) processes, including the formation of photosynthetic machinery in the chloroplast and cotyledon expansion. Phytochrome is a red (R)/far-red (FR) light photoreceptor that is involved in the various aspects

There is increasing biopharmaceutical interest in oligosaccharides and glycosylation. A key requirement for these sample types is the ability to characterize the chain length, branching, type of monomers, and importantly stereochemistry and anomeric configuration. Herein, we showcase the multi-function capability

An approach for the preparation of self-healing and injectable hydrogels based on the crystallization-driven self-assembly of carbohydrate-conjugated poly(2-isopropyloxazoline)s is reported. Hydrogelation does not require any organic solvents, as the polymers dissolve in water below their lower critical solution temperatures. The

α-Glucosidase from Aspergillus niger (AgdA; typical α-1,4-glucosidase) is known to industrially produce α-(1→6)-glucooligosaccharides. This fungus also has another α-glucosidase-like protein, AgdB. To learn its function, wild-type AgdB was expressed in Pichia pastoris. However, the enzyme displayed two electrophoretic forms due
