Dynamic light scattering and circular dichroism studies on heat-induced gelation of hard-keratin protein aqueous solutions.
Ikkai F, Naito S. Ikkai F, et al. Biomacromolecules. 2002 May-Jun;3(3):482-7. doi: 10.1021/bm010160i. Biomacromolecules. 2002. PMID: 12005518
Animal hairs consist of aggregates of dead cells filled with keratin protein gel. We succeeded in preparing water-soluble hard-keratin proteins and reconstructing the keratin gels by heat-induced disulfide linkages in vitro. Here, the roles of intermol …

A novel "trifunctional protease" with reducibility, hydrolysis, and localization used for wool anti-felting treatment.
Mei J, Zhang N, Yu Y, Wang Q, Yuan J, Wang P, Cui L, Fan X. Mei J, et al. Appl Microbiol Biotechnol. 2018 Nov;102(21):9159-9170. doi: 10.1007/s00253-018-9276-y. Epub 2018 Aug 7. Appl Microbiol Biotechnol. 2018. PMID: 30083801
Even if protease is attached by synthetic polymers, the modified protease plays a limited role in the degradation of keratin with dense structure consisting of disulfide bonds in the scales. ...This multifunctional enzyme is well-designed according to the requiremen …

Selective incorporation of selenium-75 into a polypeptide of the rat sperm tail (1).
Calvin HI. Calvin HI. J Exp Zool. 1978 Jun;204(3):445-52. doi: 10.1002/jez.1402040315. J Exp Zool. 1978. PMID: 660145
The biochemical locus of this requirement was investigated by intratesticular administration of (75Se)SeO3-2. Sperm were labeled primarily in tail keratin, a disulfide-stabilized fraction obtained by extracting isolated tails with sodium dodecyl sulfate (SDS). ...Th …

Partially carboxymethylated feather keratins. 1. Properties in aqueous systems.
Schrooyen PM, Dijkstra PJ, Oberthür RC, Bantjes A, Feijen J. Schrooyen PM, et al. J Agric Food Chem. 2000 Sep;48(9):4326-34. doi: 10.1021/jf9913155. J Agric Food Chem. 2000. PMID: 10995359
For the development of biodegradable materials with good mechanical properties from these biopolymers, disulfide bonds between the keratin molecules are needed. Therefore, cysteine residues were only partially modified by using different reagent/cysteine molar ratio …

The keratin chains of avian scale tissue. Sequence heterogeneity and the number of scale keratin genes.
Walker ID, Bridgen J. Walker ID, et al. Eur J Biochem. 1976 Aug 1;67(1):283-93. doi: 10.1111/j.1432-1033.1976.tb10660.x. Eur J Biochem. 1976. PMID: 964242 Free article.
The three major proteins of chick scale keratin were isolated as their S-carboxymethylated derivatives and shown to be similar or identical in molecular weight by gel filtration but to be distinct by amino acid analysis and gel electrophoresis. The major amino-termi …

Partially carboxymethylated feather keratins. 2. Thermal and mechanical properties of films.
Schrooyen PM, Dijkstra PJ, Oberthür RC, Bantjes A, Feijen J. Schrooyen PM, et al. J Agric Food Chem. 2001 Jan;49(1):221-30. doi: 10.1021/jf0004154. J Agric Food Chem. 2001. PMID: 11170581
Free cysteine thiol groups of keratin extracted from chicken feathers were partially carboxymethylated with iodoacetic acid (25-76% cysteine modification). ...The degree of crystallinity in the films was higher when more cysteine residues were carboxymethylated …
