Conservation and restoration of fur objects made from keratin, which is also the protein that makes up skin, feathers, nails, hooves, claws, and horns. "The way I think a lot of people understand fur versus hair is in the density of follicles," says Ross McPhee, Curator of the Department of Mammalogy at the American Museum of Natural History. "So for fur-bearing animals—which were converted into coats and so-forth—people always wanted it to be something that was very dense, so there’s the idea therefore that fur is dense, and it certainly is in [the] kinds of fur-bearers that we use for this purpose. Whereas hair is not
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
