proteinase K



Term: proteinase (or endopeptidase K)
Literally meaning: ?that enzyme which separates proteins?
Origin: Anc Greek
+????????/proteini(=protein) > ??????/protos(=first or of prime importance)
+(-???)/(-asy)(=-ase) enzyme suffix added to the name of the substrate that the enzyme  hydrolyzes eg proteinase for protein or lipase for lipids
>???-/dia-(=prefix denoting ?through?, ?apart? )
> ???/dio(two) + ??????/stasis(=halt) > ??????/histimi(=stand).
K from keratin > ?????/keras(=horn) > (genitive): ???????/keratos
Coined/History
Proteinase K  was discovered in 1974 , in extracts of the fungus Engyontium album. The name K is derived from first letter of ?keratin?  because proteinase K is able to digest native protein keratin.

Definition
Proteinase K is a protease that catalyzes the breakdown of proteins in sites of serine residues.
