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) Vitelline membrane outer layer protein I (VMO-I) In molecular biology, this entry refers to a protein domain called, the Vitelline membrane outer layer protein I (VMO-I). It is a structure found on the outside of an egg, in the vitelline membrane. The major role of the vitelline membrane is to prevent the mixing of the yolk and albumen and also act as an important anti-microbial barrier, as indicated by the high content of lysozyme in the outer layer Vitelline membrane outer layer protein I (VMO-I) binds tightly to ovomucin fibrils, which construct the backbone of the outer layer membrane. VMO-I
