Nanofitin

Nanofitine ( Affitine ) are artificial proteins which are capable of binding antigens. Affitine are structurally derived from the DNA-binding protein Sac7d the ark bacterium Sulfolobus acidocaldarius. The ability to bind to proteins, these molecules obtained by changing its near-surface amino acids. The belonging to the family of the antibody mimics Affitine be developed as a possible alternative to antibodies as tools in biochemistry.

Properties

Affitine are small molecules compared to about 20 times larger antibodies. They consist of 66 amino acids and have a molecular weight of about 7 kDa. As proteins derived from a thermophilic organism, they are characterized by a pronounced heat stability.
