Purification and properties of lactate dehydrogenase from Plasmodium knowlesi and erythrocytes of the rhesus monkey. 1986

N Saxena, and V C Pandey, and G P Dutta, and S Ghatak

Lactate dehydrogenase, E.C.1.1.1.27 (LDH) from the simian malarial parasite, Plasmodium knowlesi, and from normal rhesus monkey erythrocytes has been purified using Blue Sepharose affinity chromatography, and the properties of the purified enzyme from these two sources have been compared. The enzyme from the host and parasite were different in their kinetic properties, viz., substrate and pH optima, thermostability and isoenzymic behaviour. Partially purified LDH of the erythrocytes resolved into three isomeric bands on polyacrylamide gel electrophoresis, whereas the parasite LDH moved as a single enzyme band of different mobility from the host LDH. The molecular mass of the parasite enzyme was estimated as 117,500 daltons.

D010961 Plasmodium A genus of protozoa that comprise the malaria parasites of mammals. Four species infect humans (although occasional infections with primate malarias may occur). These are PLASMODIUM FALCIPARUM; PLASMODIUM MALARIAE; PLASMODIUM OVALE, and PLASMODIUM VIVAX. Species causing infection in vertebrates other than man include: PLASMODIUM BERGHEI; PLASMODIUM CHABAUDI; P. vinckei, and PLASMODIUM YOELII in rodents; P. brasilianum, PLASMODIUM CYNOMOLGI; and PLASMODIUM KNOWLESI in monkeys; and PLASMODIUM GALLINACEUM in chickens.
