Protein sequencing helps in determining the precise amino acid code, which is critical for understanding protein structures and functions, with wide-ranging applications across biology, chemistry, and medicine.
There are two main approaches to protein sequencing:
De novo protein sequencing, which involves elucidating the complete amino acid sequence from scratch without prior knowledge
Database searching, which compares experimentally obtained mass spectra to reference libraries to find matches and infer the likely sequence
Both approaches have their advantages and challenges in determining the complete protein sequence. |
