The polymers of fructose, levan and inulin, as well as sucrose and raffinose, are substrates for the product of the fruA gene of Streptococcus mutans GS-5. The purpose of this study was to characterize the DNA immediately flanking fruA , to explore t

The dental pathogen Streptococcus mutans persists and causes diseases in highly dynamic environments and gains a selective ecological advantage in environmental conditions that frequently exceed the limits for growth of the organism, particularly wit

Using a bacteriophage lambda library of Treponema denticola (Td) ATCC 35405 DNA, and, as a reagent, sera derived from individuals with advanced adult periodontal disease, a variety of recombinant clones producing antigens of this oral spirochete have

Streptococcus mutans GS-5 synthesizes an exo-beta-D-fructosidase, FruA, capable of degrading levans, inulins, sucrose and raffinose, with the greatest activity on levans. A previous analysis of the deduced amino acid sequence of the FruA protein reve

The complete nucleotide sequence (5,010 bp) of the fructanase gene (fruA) and flanking regions of the chromosome of Streptococcus mutans GS-5 was determined. The fruA gene appears to be the sole transcript arising from a proximal promoter. The presum

Polymers of D-fructose produced by a variety of oral bacteria are believed to function as extracellular carbohydrate reserves. Degradation of these polysaccharides in plaque following exhaustion of dietary carbohydrates is thought to contribute to th

The purpose of this study was to develop methods for the consistent production of biofilms of S. mutans containing reporter gene fusions, and to examine the expression of genes involved in sucrose metabolism in adherent populations of this organism.
