Activated by calcium (one – 5 mM), the enzyme digests proteins preferentially soon after hydrophobic amino acids (aliphatic, aromatic together with other hydrophobic amino acids). Whilst calcium ions do not impact the enzyme exercise, they are doing contribute to its steadiness. Proteins are going to be completely digested, In case the incubation time is prolonged along with the protease concentration substantial plenty of. On elimination in the calcium ions, the stability of the enzyme is lessened, but the proteolytic action remains. Proteinase K has two binding web pages for Ca2+, which is located near the active Centre, but is not directly involved with the catalytic mechanism.
