Purification and properties of a casein kinase II-like enzyme from Neurospora crassa

A serine/threonine protein kinase was partially purified from Neurospora crassa. Its physical and catalytic properties were typical of casein kinase II. In vitro, the kinase phosphorylated a calpain like protease from Allomyces arbuscula with higher affinity than a mixture of caseins.
