Abstract

Mutants of the fhuA gene of Escherichia coli K-12, which encodes a receptor protein in the outer membrane, took up ferrichrome after exposure to pronase, whereas fhuB mutants remained transport negative. The latter finding supports our previous proposal that fhuB mutants are defective in a function that residues in the cytoplasmic membrane. Cells remained completely viable after treatment with pronase, although they became sensitive to the antibiotic actinomycin.
