title: [Enzymatic formationof 4-hydroxy-2-oxovalerate using pyrazon-degrading bacteria (author's transl)].
abstract: By treatment of 2-hydroxymuconic acid with a partially purified 4-oxalocrotonate decarboxylase 4-hydroxy-2-oxovalerate could be obtained. Both forms of 4-hydroxy-2-oxovalerate, the keto as well as the enol form could be isolated.
