Part:BBa_K1364003

RBS - Antifungal D4E1 - Double terminator

D4E1 is a synthetic peptide, a linear analogue of Cecropin B AMPs (antimicrobial peptides), and has antibacterial and antifungal properties. D4E1 is composed of seventeen amino acids, and has a beta sheet conformation in solution. Lethality of D4E1 appears to be due to the peptide binding to sterols present in the fungal conidial surface, thus inhibiting the spore germination. It has also been shown that D4E1 has resistance to fungal and plant protease degradation.

Sequence and Features

This part is composed of a RBS (K780002 strong RBS), the open reading frame of D4E1 and a double terminator (B0015). This part was optimized for its expression and its secretion in Bacillus subtilis. The coding sequence of D4E1 was flanked on the N-terminal end with a signal peptide (amyE signal peptide) followed by a pro peptide, cleaved during the secretion process.
