Here we demonstrate an approach to stabilize enzymes through the orthogonal covalent attachment of albumin on the single-enzyme level. Albuminated glycoenzymes (AGs) based upon glucose oxidase and catalase fromAspergillus nigerwere prepared in this manner. Gel filtration chromatography and dynamic light scattering support modification, with an increase in hydrodynamic radius of ca. 60% upon albumination. Both AGs demonstrate a marked resistance to aggregation during heating to 90 °C, but this effect is more profound in albuminated catalase. The functional characteristics of albuminated glucose oxidase vary considerably with exposure type. The AG’s thermal inactivation is reduced more than 25 times compared to native glucose oxidase, and moderate stabilization is observed with one month storage at 37 °C. However, albumination has no effect on operational stability of glucose oxidase.
