Microsomal Nucleoprotein Particles from Pea Seedlings
Ultracentrifugal analysis of an extract of pea epicotyls, previously freed of debris and larger particles by centrifugation at 40,000 g for 10 minutes, has revealed the presence of a major component which possesses a sedimentation coefficient of 74 S. This component constitutes about 25 per cent of the TCA-precipitable material in the clarified epicotyl extract and is estimated to make up 1 to ...
متن کاملMicrosomal Nucleoprotein Particles from Pea
Much progress has recently been made in the study of the ribonucleoprotein particles associated with the microsomal fraction of cell homogenates. The shape and size of these particles as well as their distribution and organization in animal tissues have been studied with the electron microscope (1-4). They appear as round particles with diameters of 100 to 300 A in OsO4-fixed preparations of bo...
متن کاملGreening in Pea Seedlings
The effect of gibberellic acid (GA) on light-induced greening of etiolated pea plants (Pisum sativum [L.] cultivars Alaska and Progress) was characterized. Progress, a GA-deficient dwarf of Alaska, was found to accumulate chlorophyll and light harvesting chlorophyll protein associated with photosystem 11 (LHC-11) more rapidly than Alaska, Alaska treated with GA, or Progress treated with GA. A s...
متن کاملPurification and properties of amine oxidase from pea seedlings
Amine oxidase (EC 1.4.3.6) was purified from pea (Pisum sativum) seedlings with the aim of characterizing its catalytic properties. The specific activity and selectivity of the enzyme were studied with an oxygen sensor by following the kinetics of the amine oxidation reaction, catalysed by the enzyme. The enzyme catalytic constants were calculated from the transient signal of the oxygen sensor ...
متن کاملDirecting Autoimmunity to Nucleoprotein Particles
Over half a million people in the United States have sys-temic lupus. Most are women in their childbearing years. They usually have arthritis and scarring rashes, and about half have kidney involvement that may progress to renal failure. With time, there is an increasing likelihood that the brain will be involved, often resulting in loss of cognitive ability, seizures, and psychosis. Although t...
