TasA matrix protein

TasA protein

The TasA protein (also known as the major biofilm matrix component) is essential for biofilm structures and polymerizes into long fibers attached to the B. subtilis cells. ^{[1] [2]}

We designed TasA fusion proteins with CotA, CuO and EreB to immobilize our degrading enzymes in the biofilm matrix. Protein secretion into the biofilm matrix is regulated by the Sec-dependent signal recognition partice (sec-SRP) pathway. ^[3]
