pT7-B0034-csgA_linker_mfp3spep

Biofilm structural proteins in E. coli fused with mussel foot protein(Mfp) analogs bestowed the engineered biofilms with HA mineralization-promoting and interfacial binding roles. When a blue light-induced strain was used to grow functional biofilms with controlled spatial and biomass density, living mineralized materials with patterning and gradient features could be generated following a benign biomimetic HA mineralization process.


an Mfp3S protein could initiate HA mineralization and promote interfacial adhesion.CsgA–Mfp fusion proteins comprising a CsgA domain (major protein component of the E. coli biofilm31) and a C-terminal Mfp serial fusion domain were constructed.

Moreover, examination of in vivo mineralization by TEM confirmed that CsgA–Mfp3S-pep-expressing biofilms triggered denser mineral formation with more apparent crystalline features after 5 d of min-eralization . These results thus highlight the roles of the Mfp3S-pep fusion protein in promoting HA mineral formation and crystallization.
