Glucansucrase is an enzyme used by bacteria in human mouths such as Streptococcus mutans and Lactobacillus reuteri to produce long sticky biofilm chains to stick to teeth and cause tooth decay. However, the former is considered a worst offender and the latter an indicator of healthy mouth flora. The enzyme both splits sucrose into glucose and fructose as well as building the glucose chain. There is hope to make dental caries a thing of the past by knocking out this enzyme.
