Radiation Inactivation of Complex Oligomeric Enzyme Systems... 

In the case of complex and oligomeric enzymes, a dependence of on wq in the system of reverse micelles usually has few optima a wave-like profile is generally observed [45-61] (see examples in Fig. 9). A reason for such a characteristic of the dependence is the ability... 

The characteristics of the ubiquitination cascade suggest that the substrate specificity of file ubiquitin system may be extended through association of a limited number of E2 and 3 enzymes into multiple oligomeric complexes (Hochstrasser, 1996). 

D-Glucose Oxidases.—The effects of periodate oxidation upon the D-glucose oxidase of Aspergillus niger include a reduction in mass of up to 14%. This was considered in the light of changes in sedimentation and diffusion coefficients and the Stokes radius. Gel filtration studies indicated that the oxidized enzyme exists as a complex oligomerizing system. 

In a study of the periodate oxidation of r>-glucose oxidase from Aspergillus niger, 50% of the carbohydrate was removed with little effect on enzymic activity. Gel permeation chromatography results suggested that the oxidized enzyme exists as a complex oligomerizing system.
