Involvement of GroEL in nif gene regulation and nitrogenase assembly.

Journal of bacteriology - 1 Oct 1991

Govezensky D, Greener T, Segal G, Zamir A

Abstract excerpt

Several approaches were used to study the role of GroEL, the prototype chaperonin, in the nitrogen fixation (nif) system. An Escherichia coli groEL mutant transformed with the Klebsiella pneumoniae nif gene cluster accumulated very low to nondetectable levels of nitrogenase components compared with the isogenic wild-type strain or the mutant cotransformed with the wild-type groE operon. In K. pneumoniae,...
