BIOT mut 4A
BIOT is a basic design for the expression of Geobacter sulfurreducens' pilin-based electrically conductive protein nanowires (e-PNs)[1]. The system includes a tac promoter which promotes the pilin gene(pilA) to express protein monomers; the monomers are later assembled into protein nanowires by the TypeIV pilin assembly system, which is constructed from the gene cluster at the downstream of the pilin gene(figure 1). The e-PNs can generate electric potential with the presence of water molecules in the air, which can be further modified for other purposes.

In order to improve the protein nanowire, we mutated the pilA gene to enhance the productivity and output voltage. This part codes for BIOT with the pilin gene replaced by Pilin Gene mut 4A (R41E, K44D, S49D, Q55E).The electricity productivity of this part is shown in figure 2.
