We considered possible application of self-assembling peptides (SAPs). SAPs have a self-assembling ability because they are amphiphilic peptides and contain hydrophobic and hydrophilic residues. These electric charged amino acids interact with one another to form spontaneously antiparallel β-sheet in a physiochemical environmental condition.
In this projects, we used one of SAPs, RADA-16-I(RADARADARADARADA) and P11-4 (QQRFEWEFEQQ).
RADA-16-I has been established for 3-D culture of neural stem cells (NSCs) by creating nanostructures. P11-4 has been designed to form fibers at low pH and have a cytocompatibility.
Recently, SAPs have been regarded as good biological material. We considered new application methods of SAPs through discussions. Finally, we decided to make a platform of technology for constructing multi-enzyme-complex by using Self-Assembling Regions (SARs) and they are covalently linked each other through disulfide bonds. They could be assemble multiple enzymes ring (Self-AssembRing).
In the future, we will construct tool for making subunits of artificial multi-enzyme-complex by using this technology.

Self-Assembling Peptides
Recently, self-assembling peptides (SAPs) have been remarked as a biological nanostructures and hydrogel because SAPs are fit to biogenic and don’t have cytotoxicity. SAPs such as a scaffold for cell culturing and drug delivering in tissue engineering and medical technology. For example, RADA-16I self-assembles nanofibrous forming hydrogel and used for 3-D culture such as neural stem cells (NSCs), bones, cartilage tissues.Enhancement of enzymatic activity
Improvement of enzymatic activities is necessary in chemical reactions. There are some way to enhance the enzymes activities such as amino acid substitution, and compartmentation of enzymes, circularization of enzymes, and multimelarization of enzymes. For example, 2014 iGEM Heidelberg team constructed covalently linked circulated enzymes by using intein and extein and increase the stability of enzymes.Bronze
