Mono- and dithiol glutaredoxins in the trypanothione-based redox metabolism of pathogenic trypanosomes.

abstract：:Nitric oxide (NO) mediates cellular signaling pathways that regulate a plethora of physiological processes. One of the signaling mechanisms mediated by NO is through S-nitrosylation of cysteine residues in target proteins, which is now regarded as an important redox-based physiological action. Deregulation of the prot...
