Studies on the Specificity of Choline Esterase

The present investigation was undertaken to determine the relation between the structure of various substrates and the action of serum choline esterase upon them. The comparison of activities with different esters should take into account two factors : the hydrolytic velocities compared should be linear functions of time, and these velocities should be independent of substrate concentration. Th...

The Mucoproteins of the Snails, Helix Aspersa and Helix Pomatia

The problem of the structure of complex proteins containing carbohydrates in their molecule is still a subject of discussion. The fundamental questions which have been debated during the last decades and which have been the subject of many controversies are concerned with the nature of the carbohydrate group present in the molecule of these substances. Since the discovery of mucoproteins or muc...

[Small-angle x-ray-scattering studies on the substructure of Helix pomatia hemocyanin].

Hemocyanin of the snail helix pomatia was studied by small angle X-ray scattering in 0.15 M phosphate buffer pH 6. The outer portion of the scattering curve showed minima, which indicated that the hemocyanin molecule is composed of a large number of identical (or very similar) nearly spherical subunits. From the position of the minima the radius of gyration R u of the subunit was calculated to ...
