  • Title: Streptomycin resistance (rpsL) produces an absolute requirement for polyamines for growth of an Escherichia coli strain unable to synthesize putrescine and spermidine [delta(speA-speB) delta specC].
    Author: Tabor H, Tabor CW, Cohn MS, Hafner EW.
    Journal: J Bacteriol; 1981 Aug; 147(2):702-4. PubMed ID: 7021537.
    Abstract:
    The presence of certain rpsL (strA) mutations in a strain of Escherichia coli that cannot synthesize putrescine or spermidine because of deletions in ornithine decarboxylase, arginine decarboxylase, and agmatine ureohydrolase, converts a partial requirement for polyamines for growth into an absolute requirement.
