Abstract

We have previously reported that the chitin catabolic cascade in Vibrio furnissii involves multiple signal transducing systems, and that mono- and disaccharide chemoreceptors/transporters are essential components of some of these systems. This and the accompanying papers (Bouma, C. L., and Roseman, S. (1996) J. Biol. Chem 271, 33457-33467; Keyhani, N. O., Wang, L.-X., Lee, Y. C., and Roseman, S. (1996) J. Biol. Chem. 271, 33409-33413) describe some of the sugar transporters. A 13-kilobase pair fragment of V. furnissii DNA was found to impart a Glc+, Man+ phenotype to Escherichia coli ptsG ptsM mutants, and encodes the mannose transporter, ptsM, of the phosphoenolpyruvate:glycose phosphotransferase system. Unlike the E. coli mannose permease, V. furnissii IIMan is inactive with GlcNAc and Fru, and is encoded by four genes rather than three. The gene order is manXYZW, where the product of manY corresponds to IIPMan, manZ to the mannose receptor IIBMan, and manX and manW to the single E. coli gene, manX (which encodes IIIMan, viz. IIAMan). Thus, in V. furnissii, the E. coli manX equivalent comprises two genes, which are separated in the genome by two other genes of the ptsM complex. Two additional open reading frames were detected...Continue Reading
