Functional identification of a feather-degrading thermitase-like S8 serine protease from Fervidobacterium islandicum AW-1
Thermophilic species of Fervidobacterium are well known for their ability to degrade native chicken feathers, yet the specific proteases responsible for this activity at the single-enzyme level have remained unresolved because previously identified enzymes primarily acted on synthetic substrates or required synergistic...
