leishmaniasis. Spermidine synthase (SS), an important enzyme in the synthetic pathway of
polyamines in Ld, is an essential element for the survival of this protozoan. Targeting SS
may provide an important aid for the development of drugs against Ld. However, absence of
tertiary structure of spermidine synthase of Leishmania donovani (LSS) limits the
possibilities of structure based drug designing. Presence of the same enzyme in the host …
