Characterization of the Human Blood Group Glycosyltransferases GTA and GTB for the Synthesis of Blood Group Antigens

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 8, 15 April 2026.
This study presents the highly efficient heterologous production of the human blood group glycosyltransferases GTA/R176A and GTB, along with their comprehensive biochemical and kinetic characterization. Tailored enzyme cascades, involving the bacterial fucosyltransferase FutC and GTA or GTB, generate milligram quantities of various blood group ABH ...

Enzymatic acylation of di- and trisaccharides with fatty acids: choosing the appropriate enzyme, support and solvent [PDF]

open access: yes, 2002
Enzymatic synthesis of fatty acid esters of di- and trisaccharides is limited by the fact that most biological catalysts are inactivated by the polar solvents (e.g. dimethylsulfoxide, dimethylformamide) where these carbohydrates are soluble. This article

Enhanced ethyl butyrate production using immobilized lipase

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2013
In this study, the production of ethyl butyrate was investigated by using immobilized lipase enzyme in shake flasks. In order to determine optimum conditions for the production, response surface methodology was used. The model indicated the optimum conditions for maximum conversion (9.1%) at the 0.31 M substrate concentration, acid- alcohol molar ratio

Biological Degradation of Phthalates: From Bioremediation to Plastic Waste Valorization

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Phthalic acid isomers play a key role in the plastics industry, but pose significant environmental and health concerns. This review explores the microbial biodegradation of phthalates and their esters, focusing on bacterial enzymes, catabolic pathways, and cellular uptake mechanisms of phthalates.
