Alpha-keratin higher level of force before fracture. On the other hand, soft alpha-keratins, such as ones found in the skin, contain a comparatively smaller amount of disulfide bonds, making their structure more flexible. Alpha-keratin Alpha-keratin, or α-keratin, is a type of keratin found in mammals. This protein is the primary component in hairs, horns, nails and the epidermis layer of the skin. α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure. The secondary structure of α-keratin is very similar to that of a traditional protein α-helix and forms a coiled
Vitelline membrane outer layer protein I (VMO-I) has considerable activity to synthesize N-acetylchito-oligosaccharide from N-acetylglucosamine hexasaccharides but no hydrolysis activity. VMO-I is composed of 163 aa The structure consists of three beta-sheets forming Greek key motifs, which are related by an internal pseudo three-fold symmetry. Furthermore, the structure of VOMI has strong similarity to the structure of the delta-endotoxin, as well as a carbohydrate-binding site in the top region of the common fold. VMO-I revealed a unique structure of the P-prism fold, a new type of multi-sheet assembly. Vitelline membrane outer layer protein I (VMO-I) In molecular biology, this entry refers to a protein domain called, the
