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