Beta-keratin (β-keratin) is a member of a structural protein family found in the epidermis of reptiles and birds. [1] [2] Beta-keratins were named so because they are components of epidermal …

2016年3月1日 · Keratins can be classified as α- and β-types. Both show a characteristic filament-matrix structure: 7 nm diameter intermediate filaments for α-keratin, and 3 nm diameter …

During epidermal differentiation, monomers of sKAβPs (=beta-keratins) are accumulated in large quantities in cells of the upper layers and the transitional layer (1) to form bundles of dense …

Interactions between the small β-sheets in keratins provide a simple mechanism through which shape and chemical complementarity can mediate the assembly of molecules into highly …

The secondary structure of a β-keratin molecule is characterized by a central domain of 32 amino acids forming four β-sheets (Fraser et al. 1972), each of which are four amino acids long and …

2016年3月1日 · Keratins can be classified as α- and β-types. Both show a characteristic filament-matrix structure: 7 nm diameter intermediate filaments for α-keratin, and 3 nm diameter …

Keratin, complimentary fibrous proteins to collagen, is represented by two classes or molecular structures, alpha (α) and beta (β), having similar amino acid sequences and biological …

Despite amino acid differences toward N- and C-terminals all beta-keratins share high homology in their central, beta-folded region of 20 amino acids, indicated as core-box. This region is …

β-Keratin (Fig. 2b) or fibroin, the major protein in silk, has a pleated sheet structure where identical or opposed molecular strand alignments make up parallel or antiparallel beta-sheets, …

2021年9月2日 · In this chapter, we mainly introduce the hierarchical structure, the secondary structure, and the molecular structure of keratins, including α- and β-keratin, to promote the …
