Protozoal phospholipid metabolism enzymes

Protozoal phospholipid metabolism enzymes are a group of essential proteins involved in the de novo synthesis, remodeling, and degradation of phospholipids in parasitic protozoa such as Plasmodium, Leishmania, and Trypanosoma (Vial et al., 2003, NIH). These enzymes, including those of the Kennedy pathway (e.g., choline kinase and CTP:phosphocholine cytidylyltransferase) and various phospholipases, are critical for maintaining the structural integrity of parasite membranes, which undergo rapid expansion during proliferation (ASM, 2023; NIH). Because protozoan parasites often possess unique metabolic pathways or enzyme isoforms distinct from their mammalian hosts, these enzymes represent attractive targets for antiparasitic chemotherapy (NIH, 2010; ResearchGate). Drugs like miltefosine act by inhibiting these pathways, leading to disrupted membrane function, impaired signaling, and ultimately parasite death (PubMed; PatSnap, 2024). Targeting these enzymes is a proven strategy for treating diseases like leishmaniasis and is being actively explored for malaria and other protozoal infections (NIH, 2011; Elsevier).
