Coproporphyrinogenase in tobacco (Nicotiana tabacum L.).
1. Coproporphyrinogenase was extracted and purified from tobacco (Nicotiana tabacum L.). Enzyme activity was mainly located in mitochondria rather than in chloroplasts. The enzyme was purified by differential centrifugation, ammonium sulphate fractionation, calcium phosphate gel adsorption and dialysis. A 69-fold final purification was obtained. 2. An apparent K(m) value of 3.6x10(-5)m was foun...
متن کاملAcylated Steryl Glycoside Synthesis in Seedlings of Nicotiana tabacum L.
In tobacco seedlings (Nicotiana tabacum L.), glucose from supplied uridine diphosphate-[U-(14)C]glucose was first incorporated into steryl glycosides and later into acylated steryl glycosides. However, when [(14)C]cholesterol was used as substrate, the acylated steryl glycosides became labeled earlier than the steryl glycosides. With [(14)C]cholesteryl glucoside as substrate, most of the radioa...
متن کاملSteryl Glycoside Formation in Seedlings of Nicotiana tabacum L.
Particulate enzyme preparations from tobacco seedlings (Nicotiana tabacum L.) were used in the synthesis of steryl glycoside. The data obtained by measuring cholesterol-4-(14)C incorporation generally agree with results obtained with UDP-glucose-(14)C. The in vitro reaction was linear for the first 10 minutes and had a pH optimum of 7.0 to 7.4. Addition of ATP activated while UDP-glucose inhibi...
متن کاملSelection for Annual Growth Curves in NICOTIANA TABACUM L.
The cumulative growth of a plant is the result of interrelated processes, and response to selection for changes in the annual growth curve requires many physiological adjustments. Selection to modify the entire annual growth curve may therefore not be as effective as linear models may predict. Periodic growth of a population of Nicotiana tabacum L. was estimated to have heritabilities increasin...
متن کاملShading Influence on the Sterol Balance of Nicotiana tabacum L.
Tobacco plants (Nicotiana tabacum L.) were grown in the field and the apex was removed at the 42-day stage. Shading screens were set up which produced 0, 26, 67, and 90% shade. Plants were grown an additional 25 days before leaves from top, middle, and bottom stalk positions were harvested. Each leaf group was analyzed for free sterol, steryl ester, steryl glycoside, and acylsteryl glycoside. T...
