General Information | Comment | Organism |
---|---|---|
malfunction | genetic knockout mutants of both alleles are not viable, chemical targeting of LiTRYS with a drug-like compound FS-554 also leads to parasite death | Leishmania infantum |
physiological function | trypanothione synthetase, EC 6.3.1.9, but not glutathionylspermidine synthetase, EC 6.3.1.8, is essential for Leishmania infantum | Leishmania infantum |
