Component
Cytoplasmic and mitochondrial malate dehydrogenase of helminths
Cytoplasmic and mitochondrial malate dehydrogenase of helminths. Species, exposure and limitations are retained in each linked claim.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Of four benzimidazole anthelmintics tested on purified cytoplasmic and mitochondrial malate dehydrogenase from Ascaris suum, Fasciola hepatica and Moniezia expansa, mebendazole exhibited the highest percentage inhibitions, and the authors conclude that cytoplasmic and mitochondrial malate dehydrogenase regulating glycogen synthesis are the sites of mebendazole inhibitory activity while the sites for the other anthelmintics remain unclear.
