Δ9 desaturase from Trypanosoma cruzi: Key enzyme in the parasite metabolism. Cloning and overexpression.

Desaturases, key enzymes in the metabolism of fatty acids, regulate the physical and biochemical properties of membranes. They adjust the composition of saturated and unsaturated fatty acids in response to changes in the environmental. We demonstrated the existence of Δ9 desaturase activity in epimastigotes of the Trypanosoma cruzi Tulahuen strain.
