Morita, Richard Y. (Oregon State University, Corvallis), and Paul F. Mathemeier. Temperature-hydrostatic pressure studies on partially purified inorganic pyrophosphatase activity. J. Bacteriol. 88:1667-1671. 1964.-Partially purified inorganic pyrophosphatase from Bacillus stearothermophilus demonstrated increased activity at 90 C with hydrostatic pressures of 100 to 1,100 atm. At 90 C, optimal ...

Specific granules of rat atrial myocytes contain a potent fast-acting atrial natriuretic factor (ANF) and have been observed in all mammalian atria thus far examined. In this study, using a rat assay we found ANF in rat, rabbit, dog, baboon, and man. The ANF's from these species induced the characteristic diuresis and natriuresis of rapid onset and decay. The human and rat ANF's were acid-extra...

The activity of deoxythymidine kinase appears related to the proliferative ability of the cell (l-6). In adult rat liver, deoxythymidine kinase activity is virtually undetectable but appears rapidly during liver regeneration (I, 5, 7-10); the enhancement in the latter case is completely blocked by X-irradiation (II). Deoxythymidine kinase activity is also markedly enhanced in the livers of rats...

  Objective(s): Snake venoms contain complex mixture of proteins with biological activities. Some of these proteins affect blood coagulation and platelet function in different ways. Snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. In the present study, purification of anticoagulation facto...

BACKGROUND Diacylglycerol acyltransferases (DGATs) catalyze the final and rate-limiting step of triacylglycerol (TAG) biosynthesis in eukaryotic organisms. Database search has identified at least 59 DGAT1 sequences from 48 organisms, but the expression of any DGAT1 as a full-length protein in E. coli had not been reported because DGAT1s are integral membrane proteins and difficult to express an...

back ground: candida albicans is a member of the normal human microflora. c. albicans cell wall is composed of several protein and carbohydrate components which have been shown to play a crucial role in c. albicans interaction with the host immune system. major components of c. albican cell wall are carbohydrates such as mannans, β glucans and chitins, and proteins that partially modulate the h...
