Plasmodium lophurae: glucose-1-14C nd glucose-6-14C catabolism by free plasmodia and duckling host erythrocytes.
Abstract 1. 1. The in vitro catabolism of glucose-1- 14 C and glucose-6- 14 C by the avian malaria Plasmodium lophurae was studied. 2. 2. Free parasites and malaria-infected erythrocytes principallyExpand

Incorporation of 14C-amino acids by malarial plasmodia (Plasmodium iophurae). VI. Changes in the kinetic constants of amino acid transport during infection.
Abstract The majority (10 of 17) of amino acids tested entered the mature duck erythrocyte by a saturable, non-uphill transport system, whereas for the erythrocyte-free malarial parasite, PlasmodiumExpand

Incorporation of 14C-amino-acids by malaria (Plasmodium lophurae) IV. In vivo utilization of host cell haemoglobin
Abstract 1. 1. The avian malarjal parasite. Plasmodium lophurae , was grown in vivo through one asexual cycle m duck erythrocytes containing radioactive haemoglobin. 2. 2. Radioactivity was recoveredExpand

Purification of Plasmodium lophurae cathepsin D and its effects on erythrocyte membrane proteins.
The cathepsin D of Plasmodium lophurae was purified using a combination of CM-Sephadex, pepstatin-agarose and Sephadex G-100 chromatography. The plasmodial enzyme was distinct from that of the hostExpand

The glutamate dehydrogenase of Plasmodium lophurae (avian malaria).
Abstract The agent of avian malaria, Plasmodium lophurae , contains an NADP-glutamate dehydrogenase (EC 1.4.1.2) which is capable of oxidizing glutamate to α-ketoglutarate. This glutamateExpand

Glucose transport in the malarial (Plasmodium lophurae) infected erythrocyte.
SYNOPSIS Plasmodium lophurae-infected red blood cells utilized considerably greater quantities of glucose than did uninfected duckling red cells. Kinetic analysis of glucose transport showed: (A).Expand

Purine nucleoside phosphorylase of the malarial parasite, Plasmodium lophurae.
Purine nucleoside phosphorylase (EC 2.4.2.1, purine nucleoside:orthophosphate ribosyltransferase) was purified and characterized from the malarial parasite, Plasmodium lophurae, using aExpand
