Abstract
The effect of elevated growth temperature on nif mRNA synthesis, nif protein synthesis and nitrogenase activity was investigated in wild-type and NifL- strains of K. pneumoniae. Nitrogenase activity is not affected at 41.degree. C; however, nitrogenase is not synthesized at that temperature. Transcription of 3 nif operons studied is repressed at 41.degree. C. Apparently, the nifL protein is not required for repression by high temperature and repression of nif at 41.degree. C results from a reversible inactivation of the nifA gene product.This publication has 37 references indexed in Scilit:
