title: gamma-Glutamylcysteine and thiosulfate are the major low-molecular-weight thiols in halobacteria.
abstract: Six representative species of extremely halophilic bacteria were found to contain approximately millimolar concentrations of gamma-glutamylcysteine in the absence of significant glutathione. Thiosulfate also accumulated in the halobacteria, apparently as a major product of cysteine oxidation.
