T3-M-CPA

T3(BBa_K4613011) and C3(BBa_K4613012) could form protein complexes by elastin-like polypeptides(ELPs) monomers containing SpyTags and SpyCatchers. Different functional proteins can be incorporated into the polymeric scaffolds in a flexible manner due to its programmability. In this part, NAU-CHINA 2023 incorporated Mature Carboxypeptidase A(M-CPA), which is capable of hydrolyzing OTA into the non-toxic product ochratoxin α and L-α-phenylalanine(Phe) in a high degration rate. We fused M-CPA into T3 to immobilize the enzyme and increase the stability and sustainable production of M-CPA.
