چکیده
We report that a phosphoenolpyruvate-dependent phosphotransferase system, MalT, is the principal maltose transporter for Streptococcus mutans. MalT also contributes to maltotriose uptake. Since maltose and maltodextrins are products of starch degradation found in saliva, the ability to take up and ferment these carbohydrates may contribute to dental caries.

Phosphoenolpyruvate-dependent sucrose phosphotransferase activity in five serotypes of Streptococcus mutans.
An inducible phosphoenolpyruvate-dependent sucrose phosphotransferase system has been demonstrated in decryptified cell suspensions of the various common serotypes of the cariogenic microorganism Streptococcus mutans.
متن کاملCharacterization of a phosphoenolpyruvate-dependent sucrose phosphotransferase system in Streptococcus mutans.
A phosphoenolpyruvate-dependent sucrose phosphotransferase system has been identified in Streptococcus mutans. Sucrose phosphotransferase activity was inducible by sucrose and had an apparent Km for sucrose of 70 microM. The product of the sucrose phosphotransferase reaction was isolated and identified as sucrose phosphate. Additional analysis revealed that the phosphate group was on the glucos...
متن کاملIdentification and properties of distinct sucrose and glucose phosphotransferase enzyme II activities in Streptococcus mutans 6715g.
We investigated phosphoenolpyruvate-dependent phosphotransferase system enzyme II activities for sucrose and glucose in Streptococcus mutans 6715g. Two integral membrane proteins, enzyme IIscr and enzyme IIglc, each specific for its sugar substrate, sucrose or glucose, were identified by their abilities to catalyze specific sugar:sugar-phosphate exchange reactions. Some of the properties of the...
متن کاملMannitol transport in Streptococcus mutans.
A hexitol-inducible, phosphoenolpyruvate-dependent phosphotransferase system was demonstrated in Streptococcus mutans. Cell-free extracts obtained from mannitol-grown cells from a representative strain of each of the five S. mutans serotypes (AHT, BHT, C-67-1, 6715, and LM7) were capable of converting mannitol to mannitol-1-phosphate by a reaction which required phosphoenolpyruvate and Mg2+. Ma...
متن کاملMaltose and maltodextrin utilization by Bacillus subtilis.
Bacillus subtilis can utilize maltose and maltodextrins that are derived from polysaccharides, like starch or glycogen. In this work, we show that maltose is taken up by a member of the phosphoenolpyruvate-dependent phosphotransferase system and maltodextrins are taken up by a maltodextrin-specific ABC transporter. Uptake of maltose by the phosphoenolpyruvate-dependent phosphotransferase system...
