Hair Hair Hair is a protein filament that grows from follicles found in the dermis. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types, and hair care, but hair is also an important biomaterial primarily composed of protein, notably alpha-keratin. Attitudes towards different hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal
HspQ protein domain could occurs through binding of YccV itself to fully or hemimethylated DNA. In addition, studies have identified the "yccV" gene as one of three insertion sites in mini-Tn10 which suppress dnaA46 thermosensitivity. This protein domain is thought to have a SH3-like barrel structure. Additionally, the structure of a hypothetical protein in this family has been solved and it forms a beta sheet structure with a terminating alpha helix. HspQ forms a stable homodimer in solution and can form homomultimers consisting of about four monomers. The theoretical molecular mass of the HspQ protein were calculated to be 11.8 kDa. It is
