Energy metabolism enzyme (Leishmania) (null)

Energy metabolism enzymes in Leishmania species comprise a set of essential enzymes responsible for generating ATP and maintaining vital cellular functions through glycolysis, amino acid oxidation, fatty acid β-oxidation, and the electron transport chain[1][2][6]. These include, but are not limited to, hexokinase, phosphofructokinase, glyceraldehyde-3-phosphate dehydrogenase, phosphoglycerate kinase, ATP synthase, sterol 24-C-methyltransferase, pyruvate phosphate dikinase, and notably, enzymes specific to trypanothione and redox metabolism like trypanothione synthetase and trypanothione reductase[1][4][6][7]. Many of these enzymes differ significantly in sequence or structure from human equivalents, making them attractive targets for new anti-leishmanial drugs[4][5][7]. Several, such as trypanothione reductase and sterol 24-C-methyltransferase, have been prioritized for drug development, and species-specific abundance of these enzymes also serves as a biomarker for diagnostics[2][4][7]. However, targeting these enzymes may also raise challenges around metabolic plasticity and potential cross-reactivity with human enzymes[5][6][7]. Key examples of individual targets within this group: - Trypanothione reductase: Central for redox balance, unique to trypanosomatids, intensively pursued as a therapeutic target with several inhibitors under study[7]. - Sterol 24-C-methyltransferase: Essential for ergosterol synthesis; inhibited by azasterols[4]. - Hexokinase/Phosphofructokinase/Glycolytic enzymes: Involved in the parasite’s main ATP generating pathway, with expression shifting across life stages[1][6]. Because the term encompasses multiple molecular entities, for structured databases it is better to enumerate these enzymes individually per the conventions noted above.
