Expression of Klebsiella nif and his genes in Salmonella typhimurium.

Abstract

Derivatives of Salmonella typhimurium carrying F prime or P prime plasmids with Klebsiella nif and his genes had specific nitrogenase activities similar to Klebsiella in selective conditions, even to showing "hyperinduction" under argon. No evidence was obtained for catabolite repression of normal nif expression but dibutyl cyclic AMP often augmented… (More)
