概要

• 論文の詳細を見る

• 1. It was found that riboflavin was biosynthesized by various green leaves from 6, 7-dimethyl-8-ribityllumazine without participation of other carbon sources.2. It was established that the synthetic reaction, observed with a crude preparation from spinach leaves, was catalyzed by an enzyme. It has an optimum pH of 7.5 and follows the first order kinetics.3. The stoichiometry of the vitamin synthesis from the substrate was determined and a hypothetical scheme of the mechanism for the biogenesis was proposed.4. The effects of a numbr of substances on the enzyme reaction were studied.
