Optimized Biocatalytic Synthesis of 2‐Selenopyrimidine Nucleosides by Transglycosylation** [PDF]
ChemBioChem, 2021 Abstract Selenium‐modified nucleosides are powerful tools to study the structure and function of nucleic acids and their protein interactions. The widespread application of 2‐selenopyrimidine nucleosides is currently limited by low yields in established synthetic routes.

Catalysis by hen egg-white lysozyme proceeds via a covalent intermediate [PDF]
, 2001 Hen egg-white lysozyme (HEWL) was the first enzyme to have its three-dimensional structure determined by X-ray diffraction techniques(1). A catalytic mechanism, featuring a long-lived oxo-carbenium-ion intermediate, was proposed on the basis of model ...

α-Glucosidase and β-glucosidase from psychrotrophic strain arthrobacter sp. C2-2
Czech Journal of Food Sciences, 2005 In this work six psychophilic and psychrotrophic bacterial strains were screened for the presence of different glycosidase activities (α-galactosidase, α-glucosidase, β-glucosidase, α-mannosidase and β-glucuronidase).
