Proteomics/Protein Primary Structure/Sequencing Methods 1 Proteomics/Protein Primary Structure/Sequencing Methods This Section: Protein sequencing denotes the process of finding the amino acid sequence, or primary structure of a protein. Sequencing plays a very vital role in Proteomics as the information obtained can be used to deduce function, structure, and location which in turn aids in identifying new or novel proteins as well as understanding of cellular processes. Better understanding of these processes allows for creation of drugs that target specific metabolic pathways among other things. Though several methods exist to sequence proteins the two dominant methods are Mass Spectrometry and Edman ...

At about that time, methods were run could automatically be followed by another. Today, devised to provide an answer to these questions:namely, manual sequencing is rarely done. Automation has ...
