Three novel oligosaccharides synthesized using Thermoanaerobacter brockii kojibiose phosphorylase

open access: yesChemistry Central Journal, 2007
Background Recently synthesized novel oligosaccharides have been produced primarily by hydrolases and glycosyltransferases, while phosphorylases have also been subject of few studies.

Glycan Phosphorylases in Multi-Enzyme Synthetic Processes

open access: yesProtein Peptide Letters, 2017
Glycoside phosphorylases catalyse the reversible synthesis of glycosidic bonds by glyco-sylation with concomitant release of inorganic phosphate. The equilibrium position of such reactions can render them of limited synthetic utility, unless coupled with

Innovative Agents for Actinic Keratosis and Nanocarriers Enhancing Skin Penetration [PDF]

open access: yes, 2010
Actinic keratosis and cutaneous squamous cell carcinoma are of increasing importance with aging and increased ultraviolet light exposure in Western societies. Efficient and well-tolerated therapy is still a matter of concern.

Enzymatic synthesis and phosphorolysis of 4(2)-thioxo- and 6(5)-azapyrimidine nucleosides by E. coli nucleoside phosphorylases

open access: yesBeilstein Journal of Organic Chemistry, 2016
The trans-2-deoxyribosylation of 4-thiouracil (4SUra) and 2-thiouracil (2SUra), as well as 6-azauracil, 6-azathymine and 6-aza-2-thiothymine was studied using dG and E.

The origins and physical roots of life’s dual – metabolic and genetic – nature [PDF]

open access: yes, 2017
This review paper aims at a better understanding of the origin and physical foundation of life’s dual – metabolic and genetic – nature. First, I give a concise ‘top-down’ survey of the origin of life, i.e., backwards in time from extant DNA/RNA/protein ...

Anion exchange resins in phosphate form as versatile carriers for the reactions catalyzed by nucleoside phosphorylases

open access: yesBeilstein Journal of Organic Chemistry, 2020
In the present work, we suggested anion exchange resins in the phosphate form as a source of phosphate, one of the substrates of the phosphorolysis of uridine, thymidine, and 1-(β-ᴅ-arabinofuranosyl)uracil (Ara-U) catalyzed by recombinant E. coli uridine

Discovery of solabiose phosphorylase and its application for enzymatic synthesis of solabiose from sucrose and lactose

open access: yesScientific Reports, 2022
Glycoside phosphorylases (GPs), which catalyze the reversible phosphorolysis of glycosides, are promising enzymes for the efficient production of glycosides.

Insights into phosphate cooperativity and influence of substrate modifications on binding and catalysis of hexameric purine nucleoside phosphorylases. [PDF]

open access: yesPLoS ONE, 2012
The hexameric purine nucleoside phosphorylase from Bacillus subtilis (BsPNP233) displays great potential to produce nucleoside analogues in industry and can be exploited in the development of new anti-tumor gene therapies.
