Tyrosine-rich proteins in keratins
TLDR
A comparison of the contents of high-sULphur, low-sulphur and high-tyrosine proteins in various keratins taken in conjunction with parallel X-ray diffraction studies suggests that the high-tiesine proteins occur in the matrix rather than in the microfibrils.Abstract:
1. 1. In addition to high-sulphur and low-sulphur proteins a third class of proteins rich in tyrosine and glycine occurs in mammalian hard keratins and is particularly abundant in porcupine quill and echidna quill. 2. 2. A comparison of the contents of high-sulphur, low-sulphur and high-tyrosine proteins in various keratins taken in conjunction with parallel X-ray diffraction studies suggests that the high-tyrosine proteins occur in the matrix rather than in the microfibrils.read more

Structure and biochemistry of mammalian hard keratin.
TL;DR: The structure and biological formation of hard alpha-keratin are drawn together and keratinized fibres shows considerable complexity and diversity in the structural arrangement of IFs and matrix within cortical cells.

Feather Keratin: Composition, Structure and Biogenesis
Keith Gregg,George E. Rogers +1 more
TL;DR: The proteins of feather become soluble when they are treated with a combination of a disulphide bond-breaking reagent and a protein denaturant and by reaction with sodium iodoacetate.

The electron microscopy of the human hair follicle : part 1. introduction and the hair cortex
M. S. C. Birbeck,E. H. Mercer +1 more
TL;DR: The presumptive cortical cells of hair in the undifferentiated matrix of the bulb contain mitochondria, agranular vesicles, and many small dense R.N.P. particles, but no keratin, pigment granules, or endoplasmic reticulum.

Electron microscope studies of hair and wool.
TL;DR: With the emergence of this fairly-clear picture of keratinizing cells a t the fine structural level of organization, it has become of interest to investigate, with the electron microscope, the packing arrangements of the microfibrils and other structural details in these cells in the fully keratinized condition.

STRUCTURE OF α-KERATIN
TL;DR: In this paper, an investigation in progress for some time in the Textile Physics Laboratory, University of Leeds, has aimed at improved range and definition in keratin fiber X-radiograms, with the final objective of a complete analysis of the more crystalline material.

Structure of α-Keratin
TL;DR: In this paper, a high resolution focusing X-ray camera was used to obtain diffraction patterns from several native keratins and from certain heavy-atom derivatives of porcupine quill.
