A unique type of cyclic AMP-binding protein of Trypanosoma cruzi

Mol Biochem Parasitol. 1985 Jan;14(1):75-81. doi: 10.1016/0166-6851(85)90107-0.


On centrifugation on sucrose density gradients, the cyclic AMP-receptor protein of Trypanosoma cruzi was clearly resolved from the type II regulatory subunit of protein kinase from bovine heart (S20,W = 8.25 and 4.1, respectively). The binding of cyclic [3H]AMP to these two proteins was affected to different extents by several cyclic AMP analogues. Such differences between the cyclic AMP-receptor protein of T. cruzi and cyclic AMP-binding proteins of other eukaryotes might be exploitable by chemotherapy.
