Title
Synthesis of organic linkers for studying biomolecular interactions, site-specific chemical modification of peptides and its translocation studies through nanopore
Description
Biomolecules can easily recognize its corresponding partner and get bound to it, resulting in controlling various processes (immune system, inter or intracellular signaling) in biology and physiology. Bonding between two partners can be a result of electrostatic, hydrophobic interactions or shape complementarity. It is of great importance to study these kinds of biomolecular interactions to have a detailed knowledge of above mentioned physiological processes. These studies can also open avenues for other aspects of science such as drug development. Discussed in the first part of Chapter 1 are the biotin-streptavidin biomolecular interaction studies by atomic force microscopy (AFM) and surface plasmon resonance (SPR) instrument. Also, the basic working principle of AFM and SPR has been discussed.
The second part of Chapter 1 is discussed about site-specific chemical modification of peptides and proteins. Proteins have been used to generate therapeutic materials, proteins-based biomaterials. To achieve all these properties in protein there is a need for site-specific protein modification.
To be able to successfully monitor biomolecular interaction using AFM there is a need for organic linker molecule which helps one of the investigating molecules to get attached to the AFM tip. Most of the linker molecules available are capable of investigating one type of interaction at a time. Therefore, it is significant to have linker molecule which can monitor multiple interactions (same or different type) at the same time. Further, these linker molecules are modified so that biomolecular interactions can also be monitored using SPR instrument. Described in Chapter 2 are the synthesis of organic linker molecules and their use to study biomolecular interaction through AFM and SPR.
In Chapter 3, N-terminal chemical modification of peptides and proteins has been discussed. Further, modified peptides are attached to DNA thread for their translocation through the solid-state nanopore to identify them. Synthesis of various peptide-DNA conjugates and their nanopore studies have been discussed in this chapter.
