1. FUNÇÃO DO METAL BIVALENTE NA RNA TRIFOSFATASE DE TRYPANOSOMA CRUZI. / The role of the divalente metal in the RNA triphosphatase from Trypanosoma cruzi.
Cap triphosphatases act in the first step of the mRNA capping process, removing the -phosphoryl group from the 5 end of nascent RNA. Enzymes from trypanosomatids and other lower eukaryotes depend on metals for this catalysis. This contrasts with the cysteine-dependent activity of the corresponding enzymes of mammals. This difference points to these enzymes a
