Cloned(Commentary)

Cloned (Comment) Organism
recombinant expression of the enzyme under stress conditions in Trypanosoma rangeli, a trypanosome that does not perform cysteine biosynthesis de novo, results in rescue of the cysteine synthase activity and increased rates of survival of epimastigotes expressing the enzyme compared to those of wild-type parasites Leishmania braziliensis

General Information

General Information Comment Organism
physiological function upregulation of cysteine synthase and cystathionine beta-synthase contributes to Leishmania braziliensis survival under oxidative stress. Ability of Leishmania braziliensis promastigotes and amastigotes overexpressing the enzyme to resist oxidative stress, which is significantly enhanced compared to that of nontransfected cells, resulting in a phenotype far more resistant to treatment with the pentavalent form of sodium stibogluconate in vitro Leishmania braziliensis
