Proteomics and Protein Engineering

Hydrolysis (or solvolysis) of peptides and proteins involves addition of a water (or solvent) molecule across an amide bond in peptide backbones without modifying side chain structures (Fig. 2). The hydrolytic approach generates native C-terminal carboxy and N-terminal amino groups. Hence, it is particularly useful and straightforward in protein sequencing, proteomics, and protein engineering applications.

At the age of genomics and proteomics, carbodiimide mediated protein engineering is of considerable importance. Natural proteins and enzymes are readily modified or crosslinked to influence their behavior. The carbodiimide mediated inter- or intramolecular crosslinking of proteins is highly useful because no foreign molecules are introduced. Carbodiimides are zero length crosslinkers. Peptide based pharmaceuticals use carbodiimides in their manufacture and this market will increase considerably over the current low level. 

The main general consideration that can be stated so far is 1) the smoothness of the separations 2) the absence of cell prelabeling and 3) the development of biocompatible instrumentation, which allows subpopulation lineage to be produced, which are not only usable for fundamental studies such as differentiation pathways or apoptosis studies, but also for transplantation or genetic engineering. One must have in mind that the cell is definitively the place, home, and native localization of genes and proteins. The possibility of rapid, nondestructive separation, purification, and characterization of cells (cellulomics) opens fabulous dimensions for proteomics and genomics.
