NIH-funded research R01 grant

Understanding how Streptococcus mutans builds sugars that drive tooth decay

Official title: Structural and Functional Studies on the Glucosyltransferases of the Dental Caries Pathogen Streptococcus mutans

Funded at University of Alabama at Birmingham · NIH-11333043 · Data updated 2026-11-12

Researchers will study how the tooth decay bacteria S. mutans makes different sugar polymers, aiming to uncover why these polymers help the bacteria stick to teeth and cause dental caries.

What this research studies

This project focuses on the enzymes GtfB, GtfC, and GtfD in Streptococcus mutans to reveal how they produce soluble and insoluble glucans from sucrose. By examining the molecular mechanisms and functional domains, scientists hope to map how each enzyme contributes to biofilm formation and virulence on teeth. The work combines structural biology and biochemistry to connect enzyme activity with the progression of dental caries in humans. Findings could inform new strategies to prevent or disrupt harmful biofilms. The research is conducted at the University of Alabama at Birmingham with a goal of translating basic insights into better oral health outcomes.

Why it matters

Potential benefit: Better understanding of how dental plaque forms could lead to new preventive or therapeutic approaches to reduce tooth decay.

How similar studies have gone: Prior work has characterized Gtf enzymes and their role in biofilms, but the detailed mechanism of producing different glucans remains incompletely understood.
