Proteinase K from Tritirachium album >=30 units/mg protein
MilliporeSigmaProteinase K (PK) from fungi, Tritirachium album encodes a 40 kDa protein. The N-terminal propeptide region shows homology with bacterial subtilisin. PK crystallizes even under microgravity conditions on the space shuttle mission. PK is an effective protein system for studying protein engineering…
