The Enzymic Degradation of Adenosinetriphosphate

In vitro capacity and in vivo antioxidant potency of sedimental extract of Tinospora cordifolia in streptozotocin induced type 2 diabetes

Objective: The role of herbs against the free radicals have been put forth recently in combating many diseases. The aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of Tinospora cordifolia (SETc). Materials and Methods: SETcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, hydr...

An Adenosinetriphosphate-activated Hemolytic System by Blanche Ann Borek and Max Bovarnick

In 1954 Synder and his coworkers (1) reported that water hemolysates of rabbit erythrocytes were capable of lysing whole rabbit cells if adenosinetriphosphate was also present in the system. Sheep cell hemolysate and adenosinetriphosphate did not have a corresponding effect on sheep erythrocytes. Subsequently, one of the group, (M.R.B.),' found that rabbit cell hemolysate also caused hemolysis ...

The enzymic degradation of laminarin. 2. The multicomponent nature of fungal laminarinases.

Lysine degradation through the saccharopine pathway in mammals: involvement of both bifunctional and monofunctional lysine-degrading enzymes in mouse.

Lysine-oxoglutarate reductase and saccharopine dehydrogenase are enzymic activities that catalyse the first two steps of lysine degradation through the saccharopine pathway in upper eukaryotes. This paper describes the isolation and characterization of a cDNA clone encoding a bifunctional enzyme bearing domains corresponding to these two enzymic activities. We partly purified those activities f...

Phospholipid Degradation in Membranes of Isolated Soybean Lipid Bodies

Membrane degradation was observed in lipid bodies isolated from soybean seeds and incubated at 30°C for 6and 18-day periods. Three events occurred during degradation. Phosphatidylcholine and phosphatidylethanolamine (PE) were converted to phosphatidic acid presumably by phospholipase D, but PE decreased even in the absence of phospholipase D enzymic activity. A substance that cochromatographed ...
