Trypanosoma cruzi epimastigote forms possess a Ca2+-calmodulin dependent protein kinase
Trypanosoma cruzi epimastigote forms showed a tightly bound Ca2+-calmodulin-dependent protein kinase activity, which could be partially extracted from membranes and axonemes. The enzyme is constituted by subunits which were autophosphorylated in the absence of exogenous substrates. An antibody again...
