A Ca2+/calmodulin (CaM)-dependent multifunctional protein kinase has been isolated from Aspergillus nidulans and purified to homogeneity. Unlike any CaM-dependent multifunctional protein kinase described previously, the native enzyme from Aspergillus behaves as a monomer. The calculated molecular weight is 41,200. NaDodSO4/PAGE reveals a single protein band with an apparent Mr of 51,000. Two-di...
