Each protein has a characteristic number and sequence of amino acid residues. The primary structure of a protein determines how the protein folds into a unique three-dimensional structure secondary, tertiary, and quaternary structures, which in turn determines the biological function of the protein.
The determination of protein sequence information can be used to design oligonucleotide probes complementary to the predicted gene sequence. These nucleic acid probes play an important role in cloning new genes encoding low-abundance proteins. For example, genes encoding many important drug proteins used in the clinic. Protein sequencing analysis can directly identify post-translational modifications that cannot be predicted from gene sequences, characterize recombinant proteins, and fragments of natural and recombinant proteins for structural and functional studies. Recombinant protein drugs can also be characterized to ensure that the expressed product conforms to the predicted structure, and to evaluate the quality and purity of the product to be highly consistent.
