Dear Conny,

Please search for analog questions in R.G (p.e. link 2 in my answer) and , in other part , here are these links (see 1,2,3) with the wished reference. Have you the possibility to contact the Uni library e.g. librarian in Düsseldorf for a pdf file copy of the Biochem Zeitschrift?

1. Warburg, O. and W. Christian (1942) Isolation and crystallization of enolase. Biochem. Z. 310:384-421.

My own copy (Library Uni Freiburg) is no longer avaible in my archives.

Sometimes you can find 1941 or 1941/1942 for the publication's year of this paper.
