Rousset, JP, Gilson, E and Hofnung, M (1986) malM, a new gene of the maltose regulon in Escherichia coli K12. II. Mutations affecting the signal peptide of the MalM protein. J. Mol. Biol. 191:313-20

Abstract

malM is the last gene of the malK-lamB-malM operon of Escherichia coli K12. It encodes a periplasmic protein. Mutations affecting the hydrophobic core of the N-terminal extension of the MalM protein have been isolated. They result in an increase in amount and specific activity of a MalM-LacZ hybrid protein. This result confirms that the signal peptide of the MalM protein is functional.
