Part:BBa_K4147002
Expression construct for (CBD)2-DrsB1: Dermaseptin AMP from Phyllomedusa bicolor
This part contains the linear construct BBa_K4147001 for (CBD)2-DrsB1 which already counts with a PelB signal peptide on the N- terminal as well as a 6X-His tag at the end of the dermaseptin CDS (C- terminal) for later protein purification. This composite construct includes a LacI regulated promoter. Additionally, it contains an RBS under the part name BBa_B0032. Finally, it has a double terminator (BBa_B0015) to ensure correct termination. As a linear 1075 bp construct, it contains the RFC10 prefix and suffix, making the part compatible with other iGEM parts.
Among a wide range of AMPs, polycationic dermaseptin peptides are produced by the skin glands of the frog Phyllomedusa bicolor [1]. It supplies both antibacterial and antifungal protection to a broad range of plant pathogens but shows no toxic effects on plant and mammalian cells [2]. This peptide of molecular weight of 22.1 kDa contains a tandem repeat of a chitin binding domain (CBD) as an improvement of dermaseptin-b1 gene (AKA MsrA2)(BBa_K2577001) which binds to chitin fungal cell wall, thereby increasing the lytic activity of the catalytic dom
