Biosynthesis of Sulfoquinovosyldiacylglycerol in Higher Plants: The Incorporation of SO(4) by Intact Chloroplasts in Darkness.
Intact spinach chloroplasts incorporated (35)SO(4) (2-) into sulfoquinovosyldiacylglycerol in the dark at rates equivalent to those previously reported for illuminated chloroplasts provided that either ATP itself or an ATP-generating system was added. No additional reductant was necessary for SQDG synthesis by chloroplasts. The optimal concentration of ATP was between 2 and 3 millimolar. Rates ...
متن کاملPantothenate biosynthesis in higher plants.
Pantothenate (vitamin B5) is a water-soluble vitamin essential for the synthesis of CoA and ACP (acyl-carrier protein, cofactors in energy yielding reactions including carbohydrate metabolism and fatty acid synthesis. Pantothenate is synthesized de novo by plants and micro-organisms; however, animals obtain the vitamin through their diet. Utilizing our knowledge of the pathway in Escherichia co...
متن کاملThe biosynthesis of sterols in higher plants.
1. [2-(14)C]Mevalonate was incorporated into squalene and the major phytosterols of pea and maize leaves; it was also incorporated into compounds belonging to the 4,4-dimethyl and 4alpha-methyl steroid groups and which may be possible phytosterol intermediates. 2. l-[Me-(14)C]Methionine was incorporated into the major sterols and also into the 4,4-dimethyl and 4alpha-methyl steroid groups. No r...
متن کاملTetrahydrofolate biosynthesis and distribution in higher plants.
One-carbon transfer reactions are mediated by H4F (tetrahydrofolate), a soluble coenzyme (vitamin B9) that is synthesized de novo by plants and microorganisms, and absorbed from the diet by animals. H4F synthesis in plants is quartered between the plastids, the cytosol and the mitochondria, a spatial distribution that is not observed in the other organisms and that suggests a complex intracellu...
متن کاملVitamin B6 biosynthesis in higher plants.
Vitamin B6 is an essential metabolite in all organisms. It can act as a coenzyme for numerous metabolic enzymes and has recently been shown to be a potent antioxidant. Plants and microorganisms have a de novo biosynthetic pathway for vitamin B6, but animals must obtain it from dietary sources. In Escherichia coli, it is known that the vitamin is derived from deoxyxylulose 5-phosphate (an interm...
