 To express heterologous genes in a stage-specific manner, we constructed a transformation vector for Trypanosoma cruzi containing a selection gene (hyg) and a reporter gene (luc) flanked by sequences of the multicopy 1f8 gene arranged so as to provide a trans-splicing acceptor site to hyg and a putative polyadenylation signal to luc. The intergenic region(More)
Agmatinase is an enzyme that catalyzes the hydrolysis of agmatine, a compound that is associated with numerous functions in the brain of mammalian organisms such as neurotransmitter, anticonvulsant, antinociceptive, anxiolytic and antidepressant-like actions. To date the only characterized agmatinases with significant enzymatic activity were extracted from(More)
Agmatine (1-amino-4-guanidinobutane) plays an important role in a range of metabolic functions, in particular in the brain. Agmatinases (AGMs) are enzymes capable of converting agmatine to the polyamine putrescine and urea. AGMs belong to the family of Mn2+-dependent ureahydrolases. However, no AGM from a mammalian source has yet been extracted in(More)
Agmatine, a precursor for polyamine biosynthesis, is also associated with neurotransmitter, anticonvulsant, antineurotoxic and antidepressant actions in the brain. This molecule results from the decarboxylation of l-arginine by arginine decarboxylase, and it is hydrolyzed to urea and putrescine by agmatinase. Recently, we have described a new protein that(More)
