Structural characterization and active site prediction of keratinase from Bacillus flexus.

Sixteen keratinolytic bacteria were isolated from poultry farm soil samples. The highest keratinlytic enzyme producers of Bacillus flexus was confirmed with 16S rRNA sequence analysis. It is of interest to understand the binding efficiency of the modelled keratinase from Bacillus flexus with different substrates using molecular docking studies. Data provides insights for the identification of substrate recognition patterns, and the development of suitable enzymes to improve their use in keratin degradation.
