Colonization Device
Purpose
One big challenge of probiotics is their survival in intestine we respond to this challenge by expressing gene adrA responsible for manufacturing the second messager c-di-GMP, a magic molecule that leads to inhibition of motility and increase of adhesion and division of E.coli.
Outline
AdrA protein can convert GTP into c-di-GMP, a magic second massager that, besides promote the production of cellulose(for more details, see our celluose synthesis device), can reduce the expression of flagella and acute virulence gene simultaneously. In the same time, c-di-GMP can facilitates the synthesis of various adhesins and exopolysaccharides and can facilitates the proteolysis of replication inhibitors. As a result, AdrA makes cells become adhesive and promote the formation of biofilm, making the bacteria gain advantages to survive in the hostile environment of intestine.
