Role of Keratinases in Dermatophytosis
Dermatologica, 2009Hartley strain, male guinea pigs were cutaneously infected at the nape of the neck with T. mentagrophytes var. granulosum. Guinea pigs were also immunized with keratinases (I and II) in Freund’s complete adjuvant. Guinea pigs sensitized by cutaneous infection developed dermal reactivities of the delayed type, the most intense reaction being to the heat-

Keratinase of Doratomyces microsporus
Applied Microbiology and Biotechnology, 2000The fungus Doratomyces microsporus produced an extracellular keratinase during submerged aerobic cultivation in a medium containing a protein inducer for enzyme synthesis. The keratinase was purified to homogeneity using hydrophobic interaction chromatography followed by gel chromatography. The molecular weight was estimated to be 33 kDa (from SDS-PAGE

Inhibition of keratinases byα 2-Macroglobulin
Experientia, 1972Sera von Patienten mit Dermatophytosis und von Gesunden (Saugline und Erwachsene) hemmten die Keratinasen vonTrichophyton mentagrophytes. Der Inhibitor wurde von Neugeborenen-Serum isoliert und als α2-Makroglobulin identifiziert.

Research progress on the degradation mechanism and modification of keratinase
Applied Microbiology and Biotechnology, 2023Keratin is regarded as the main component of feathers and is difficult to be degraded by conventional proteases, leading to substantial abandonment. Keratinase is the only enzyme with the most formidable potential for degrading feathers. Although there have been in-depth studies in recent years, the large-scale application of keratinase is still ...

Extremophiles, 2020
A new keratinase producer, Bacillus sp. BK111, isolated from a poultry feather was identified as Bacillus zhangzhouensis, which is the first report for its keratinolytic activity. The keratinase production was optimized, followed by the enzyme purification and characterization using biochemical assays.

IMMUNOLOGICAL STUDIES OF AN EXTRACELLULAR KERATINASE
The Journal of Dermatology, 1983ABSTRACTThe extracellular keratinase from M. canis was purified using ion exchange chromatography and gel filtration. The purified enzyme showed a single protein band on sodium dodecyl sulfate‐polyacrilamide gel electrophoresis. A molecular weight of approximately 45,000 was determined by SDS‐electrophoresis.Anti‐body directed against the purified ...

Production and Applications of Keratinases in Industry
Pakistan Journal of Biochemistry and Biotechnology, 2023Keratin is an insoluble protein with fibrous structure. It is mainly found in hair,feathers,nail,wool and horn of various animals. These animal accessories can be utilized as animals feed, amino-acids and fertilizers. This insoluble protein is very difficult to degrade and has extreme stability because it has disulfide bonds, hydrogen and hydrophobic ...

Intracellular keratinase ofTrichophyton gallinae
Medical Mycology, 1987Trichophyton gallinae could grow on agar medium containing chicken feathers as sole sources of carbon and nitrogen, but it could not utilize human or guinea pig hair. The fungus grows rapidly when feather keratin solubilized in dimethyl sulphoxide was included in the growth medium.
