Abstract
A mutant was isolated from E. coli-B which can grow on putrescine as the sole source of C and N. This mutant contains a constitutive putrescine a-ketoglutarate transaminase and can be induced for the enzymes responsible for the conversion of gamma-aminobutyraldehyde to succinate. The intracellular putresine of this mutant could be nearly quantitatively removed by N starvation. This removal of intracellular putrescine did not damage the reproduction of T2 in these cells.Keywords
