Chloroplasts contain high amounts of monogalactosyldiacylglycerol (MGDG) and
digalactosyldiacylglycerol (DGDG) and low levels of the anionic lipids …

In recent years, significant progress has been made in understanding the geometric and
electronic structures of the active sites of non-heme iron enzymes and the contributions of …

The polyunsaturated fatty acids linoleate and alpha-linolenate are important membrane
components and are the essential fatty acids of human nutrition. The major enzyme …

▪ Abstract Desaturation of a fatty acid first involves the enzymatic removal of a hydrogen from
a methylene group in an acyl chain, a highly energy-demanding step that requires an …

Dioxygen activation by metalloenzymes generally proceeds through one of two
fundamentally different routes. Some enzymes, such as the ferric ion containing intradiol …

Revised Manuscript Received August 15, 1994® abstract: The eukaryotic fatty acid
desaturases are iron-containing enzymes that catalyzethe NAD-(P) H-and 02-dependent …

▪ Abstract The contribution of membrane lipids, particularly the level of unsaturation of fatty
acids, to chilling sensitivity of plants has been intensively discussed for many years. We …

The bulk of the World's lipids are produced by plants and, of these, the acyl iipids form the
largest part. Thus, the importance of plant fatty acid biosynthesis hardly needs emphasising.

The very high proportions of trienoic fatty acids found in chloroplast membranes of all higher
plants suggest that these lipid structures might be essential for photosynthesis. We report …

The overall fatty acid composition of leaf lipids in a mutant of Arabidopsis thaliana was
characterized by reduced levels of polyunsaturated 18-carbon fatty acids and an increased …
