Our goal is to engineer a common yogurt bacteria, Lactobacillus bulgaricus, so that it will express the 20aa peptide p1025. A |clinical study reports that p1025 is good for your teeth (p1025 reduces oral colonization of a Streptococcus mutans, a tooth-decaying bacterium).
Stage 1: Construction of p1025 fusion peptide and expression of gene in E. coli. This is an intermediate step to evaluate gene function and protein secretion/efficacy.
Stage 2: Binding Assay - see if the p1025 produced by E.coli inhibits binding of S. mutants to HA beads.
