Some factors affecting the Hill reaction activity in cotton chloroplasts.
A method of plant culture was developed for growing large leaves of glandless cotton on single stems. Chloroplasts isolated from these leaves actively reduced ferricyanide when assayed for the Hill reaction. Hill reaction activity increased 133% when the 0.5 m sucrose isolation medium was replaced with 10% (w/v) polyethylene glycol, both buffered at pH 7.6. The presence of 2 or 5% (w/v) bovine ...
متن کاملSome factors affecting kidney transamidinase activity in rats.
Although it is well established that only two enzymes, transamidinase and guanidoacetate methylpherase, are directly involved in the formation of creatine (l-4), almost nothing is known about the regulation of creatine synthesis. Since various diseases alter creatine metabolism (5), it is possible that a study of transamidinase and guanidoacetate methylpherase activities in some of these diseas...

متن کاملFactors affecting the flight capacity of Tetrastichus planipennisi (Hymenoptera: Eulophidae), a classical biological control agent of Agrilus planipennis (Coleoptera: Buprestidae).
The dispersal characteristics of a biological control agent can have direct implications on the ability of that agent to control populations of a target host. Tetrastichus planipennisi Yang (Hymenoptera: Eulophidae) is a parasitic wasp native to eastern Asia that has been introduced into the United States as part of a classical biological control program against the emerald ash borer Agrilus pl...

Depue, Robert H. (Hahnemann Medical College, Philadelphia), and Albert G. Moat. Factors affecting aspartase activity. J. Bacteriol. 82:383-386. 1961.-Cells of Escherichia coli grown in a glucose-mineral salts medium contain about one-fifth the amount of aspartase activity observed in cells grown in a yeast extract-peptone medium. The aspartase activity of the cells grown in glucose-salts medium...
