ON THE RELATION BETWEEN THE RETINENE REDUCTASE AND FLAVIN CONTAINING ENZYME

Abstract

1. Pteroylglutamic acid inhibited the regeneration of retinene1 from vitamin A₁.
2. The yield of retinene₁ and vitamin A₁ was increased by adding DPN or DPN and FAD to the enzyme system.
3. The yield of retinene₁ and vitamin A₁ was decreased in phlo-rhizinized frogs.
