Fat Metabolism in Higher Plants: XLVII. The Effect of Nitrite and Other Anions on the Formation of Unsaturated Fatty Acids by Isolated Chloroplasts.

abstract：:Plants contain several genes encoding thioredoxins (Trxs), small proteins involved in the regulation of the activity of many enzymes through dithiol-disulfide exchange. In addition to chloroplastic and cytoplasmic Trx systems, plant mitochondria contain a reduced nicotinamide adenine dinucleotide phosphate-dependent T...
