説明

1. The metablism of malonate was investigated using the cell suspension of Mycobacterium tuberculosis avium.<br> 2. The cell suspension oxidizes malonate, which is at first step decarboxylated into acetate.<br> 3. The enzyme taking part in the decarboxylation is an adaptive enzyme, the formation of which in the streptomycin-sensitive cells is inhibited in the presence of Streptomycin.<br> 4. The cell suspension of the streptomycin-resistant substrain oxidizes adaptively malonate and benzoate along S-shaped curves similar to the streptomycin-sensitive cells and these oxidations are not inhibited in the presence of Streptomycin.
