Proline is one of the ambivalent amino acids, meaning that it can be inside or outside of a protein molecule. Due to its unique structure, proline occurs in proteins frequently in turns or bends, which are often on the surface. The structure shown is of the amino acid in the ionization...

NMR solution structure of a dsRNA binding domain from Drosophila staufen protein reveals homology to the N-terminal domain of ribosomal protein S5. The double-stranded RNA binding domain (dsRBD) is an approximately 65 amino acid motif that is found in a variety of proteins that interact with do...
Proline is unique among amino acids due to its cyclic structure. It contributes to protein structure, collagen synthesis, and helps stabilize protein tertiary structure. Conclusion: The 20 different amino acidsencode the vast array of proteins that are essential for life. Each amino acid serves a...
In general, the primary amino acid sequence of a polypeptide chain is thought to encode all the information necessary to determine the final folded structure of a protein. However, the contributions made by individual amino acid residues... FrederickW.Dahlquist,LawrenceMcIntosh,JirongLu,... - Macm...
