Enzymes that require manganese for proper function [4].

S. No.	Enzyme	Function
1	Prolidase	Collagen recycling (Enzyme capable of degrading dipeptides)
2	Arginase	Krebs-Henseleit urea cycle (Final enzyme of the urea cycle)
3	Superoxide dismutase	Antioxidant (An enzyme that alternately catalyzes the dismutation of the superoxide radical into either ordinary molecular oxygen or hydrogen peroxide)
4	Glycosyl tranferases	Glycosaminoglycan synthesis (Enzymes that establish natural glycosidic linkages)
5	Glutamine synthetase	Glutamine synthesis (Plays an essential role in the metabolism of nitrogen by catalyzing the condensation of glutamate and ammonia to form glutamine)
6	Isocitrate dehydrogenase	Krebs cycle (Catalyzes the oxidative decarboxylation of isocitrate, producing alpha-ketoglutarate and CO₂)
7	Pyruvate carboxylase	Gluconeogenesis (It catalyzes the physiologically irreversible carboxylation of pyruvate to form oxaloacetate)
8	Phosphoenolpyruvate carboxykinase	Gluconeogenesis (It converts oxaloacetate into phosphoenolpyruvate and carbon dioxide)
