Temperature sensitivity of the regulation of nitrogenase synthesis by Klebsiella pneumoniae.

Zhu J, Brill WJ

Abstract

Temperature sensitivity of the regulatory protein coded by nifA prevents the organism from utilizing N2 at 37 degrees C. The purpling of 6-cyanopurine, a function of nifA expression, also is thermolabile.
