Effect of cholesterol on macromolecular synthesis and fatty acid uptake by Mycoplasma capricolum.
The rates of protein and lipid synthesis of Mycoplasma capricolum were essentially synchronous during growth and depended on the sterol supplement in the media increasing in the order cholesterol (0.5 microgram/ml) < lanosterol (10 microgram/ml) < lanosterol (10 microgram/ml) + cholesterol (0.5 microgram/ml) < cholesterol (10 microgram/ml). The effect of lanosterol plus low cholesterol on macro...
متن کاملPhospholipids as acyl donors to membrane proteins of Mycoplasma capricolum.
Mycoplasma capricolum, a procaryotic sterol and fatty acid auxotroph, contains a large number of membrane proteins covalently modified by both saturated and unsaturated fatty acids (Dahl, C.E., Dahl, J.S., and Bloch, K. (1983) J. Biol. Chem. 258, 11814-11818). Pulse-chase experiments show that the radioactivity in the fatty acid moieties of the acyl proteins increases rather than decreases duri...
متن کاملUptake of fatty acids by Mycoplasma capricolum.
The energy requirements for fatty acid uptake by Mycoplasma capricolum were studied. Fatty acid transport and esterification to phospholipid appeared to be tightly coupled, since there was little intracellular accumulation of free fatty acid. Uptake was blocked by iodoacetate, n-ethylmaleimide, and p-chloromercuribenzoate. Glucose, glycerol, and potassium ions were necessary for fatty acid upta...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
