Metabolism of polysaccharides by the Streptococcus mutants dexB gene product.

Journal of general microbiology - 1 Sept 1993

Whiting G C, Sutcliffe I C, Russell R R

Abstract excerpt

The Streptococcus mutans dexB gene, a member of the multiple sugar metabolism (msm) operon, encodes an intracellular glucan 1,6-alpha-glucosidase which releases glucose from the non-reducing terminus of alpha-1,6-linked isomaltosaccharides and dextran. Comparison of primary amino acid sequences showed strong homology to Bacillus oligo-1,6-glucosidases and, like these enzymes, DexB was able to release free glucose...
