Abstract
Chromatium species produced the novel biological thiol glutathione ami de, gamma-L-glutamyl-L-cysteinylglycine amide (GASH), when grown photo heterotrophically. GASH was largely converted to the corresponding per thiol during photoautotrophic growth on sulfide, suggesting that GASH may have a function in anaerobic sulfide metabolism. This unprecedente d form of glutathione metabolism was probably present in anaerobic anc estors of modern cyanobacteria acid purple bacteria.
