The polyamines putrescine, spermidine and spermine are organic cations shown to participate in a bewildering number of cellular reactions, yet their exact functions in intermediary metabolism and specific interactions with cellular components remain largely elusive. Pharmacological interventions have demonstrated convincingly...

We used the dioecious tree, Populus cathayana, as a model species to study plants' physiological and biochemical responses to copper (Cu) stress, exogenous putrescine (Put) treatment and their interaction. Although males accumulated higher Cu concentrations in leaves than did females...

The phosphate starvation response in bacteria has been studied extensively for the past few decades and the phosphate-limiting signal is known to be mediated via the PhoBR two-component system. However, the global DNA binding profile of the response regulator PhoB...

EmrE, a multidrug antiporter from Escherichia coli, has presented biochemists with unusual surprises. Here we describe the transformation of EmrE, a drug/H(+) antiporter to a polyamine importer by a single mutation. Antibiotic resistance in microorganisms may arise by mutations at...

The TcPOT1.1 gene from Trypanosoma cruzi encodes a high affinity putrescine-cadaverine transporter belonging to the APC (amino acid/polyamine/organocation) transporter superfamily. No experimental three-dimensional structure exists for any eukaryotic member of the APC family, and thus the structural determinants critical for...
