摘要：
The possibility was examined whether weak external electromagnetic radiation can affect the parameters of enzymic reactions. It was found that, in a system involving an aqueous solution of concanavalin A, glucose, and erbium salt exposed to helium-neon laser light of a wavelength of 633 nm, epimers of glucose: allosa, mannose, and galactose are formed. The effect observed was found to represent a photoinduced enzymic reaction in which the protein dissolved in water converts the glucose associated with it into epimers by the action of electromagnetic radiation. The photoepimerase activity of concanavalin A was established for the first time.
