Title: Effect of <scp>L</scp>-methionine-<scp>DL</scp>-sulfoximine on acetylene reduction and vesicle formation in derepressed cultures of <i>Frankia</i> strain D11

GS activity, detected in cell-free extracts of D11, was higher in N 2 -fixing than in nonfixing conditions. These facts suggested that nitrogenase biosynthesis in Frankia was probably regulated by GS, GOGAT, or a product of their reaction, but regulation of GS by an adenylylation–unadenylylation system was probably not involved. Similarities between Frankia and Anabaena cylindrica were stressed.Read More
