A New Transaminase of Corynebacterium diphtheriae

  • An Erratum to this article was published on 14 June 1958


ACCORDING to Shemin et al. 1,2 δ-aminolævulinic acid is not only utilized for porphyrin synthesis, but has also to be considered as an intermediate in the formation of purines. Very little is known at present about the enzymes responsible for this conversion. Shemin suggests the deamination of δ-aminolævulinic acid. Recently, Kowalski et al. 3 succeeded in demonstrating a δ-aminolævulinic acid transaminase system in mammalian tissues.
