Usage
In the process of protein purification by ATPs, we can use the amphiphilicity of BslA to change the hydrophilicity of fluorescent protein, so that fluorescent protein can only show fluorescence in the organic phase/aqueous phase, so as to achieve a high-efficiency and low-cost protein purification method.
Our team used the amphiphilicity of BslA to enhance the antibacterial/targeting effect of LL37 antimicrobial peptide and RGD-targeted peptide
Biology
BslA is a structurally defined bacterial hydrophobin that was found in the biofilm of Bacillus subtilis.
It helps the assembling of TasA (an exopolysaccharide and an amyloid fiber-forming protein), the component of the biofilm matrix. BslA is composed of an Ig-type fold with the addition of an unusual, extremely hydrophobic “cap” region. The central hydrophobic residues of the cap are essential to allow a hydrophobic, nonwetting biofilm to form as they control the surface activity of the BslA protein.[1]
Design Consideration
The construction includes: BslA with a TEV linker（GGTGGTGGCGGCAGCGGCGGAGGCGGTAGT）
