Diacylglycerol acyltransferase in maturing sunflower seeds.

Developing sunflower seeds exhibit a high diacylglycerol acyltransferase (DAGAT, EC 2.3.1.20) activity. The distribution of the enzyme has been studied in subcellular fractions prepared by differential centrifugation of seed homogenate. Its activity was characterized using [1-(14)C]oleoyl-CoA and diolein dispersed in Tween 20. Some properties of the microsomal fraction of DAGAT were investigate...

Cessation of assimilate uptake in maturing soybean seeds.

In vitro assimilate uptake and metabolism were evaluated in embryos of known age isolated from seeds at mid-podfilling through physiological maturity. The capacity of isolated Wye soybean embryos to take up exogenous [(14)C]sucrose dropped nearly 4-fold in less than 1 week at incipient cotyledon yellowing. This drop in rate of sucrose uptake coincided with cessation of seed growth as well as ra...

O-lysophospholipid Acyltransferase from the Microsomes of Developing Safflower Seeds

Acyl-CoA:O-lysophospholipid acyltransferase activity was measured in extracts of developing safflower (Carthamus tinctoriis var. UC-1) seeds. Acyltransferase activity was present in all subcellular fractions. The microsomal acyltransferase activity was solubilized with either 30 mM-noctylglucoside, 1% deoxycholate, or 100 isM lysophosphatidyicholine. The pH optimum of the lysophosphatidylcholin...

Heterogeneity of catalase in maturing and germinated cotton seeds.

To investigate possible charge and size heterogeneity of catalase (EC 1.11.1.6) in cotton (Gossypium hirsutum L. cv Deltapine 62), extracts of cotyledons from different developmental ages were subjected to nondenaturing polyacrylamide gel electrophoresis and isoelectric focusing. Special precautions (e.g. fresh homogenates, reducing media) were necessary to prevent artefacts due to enzyme modif...
