title: Comparison of the glucosyltransferases of Streptococcus mutans gs-5 to a non-cariogenic mutant.
abstract: The extracellular glucosyltransferase (GTF) enzymes of Streptococcus mutans GS-5 and avirulent mutant GS-511 were fractionated using agarose and DEAE-cellulose columns. GTF of GS-5 produced both water-soluble and -insoluble glucans, while those of GS-511 made soluble products almost exclusively. Nearly all (98%) of the small amount of insoluble GTF enzyme made by GS-511 was bound to the cell wall.
