Photoactive ATP Dependent Glutamine Synthetase from Chloroplasts of Setaria italica Beauv
نویسندگان
چکیده
Light and ATP dependent glutamine synthetase (E. C. 6.3.1.2) activity was predominantly located in the mesophyll chloroplasts of Setaria italica Beauv., a C4 plant. ATP served the kinetic requirement while ADP exerted inhibitory effects on the enzyme activity. Sucrose stimulated the enzyme activity both in the light and in the dark. The inhibitors of both the cyclic and noncyclic photophosphorylation have suppressed the enzyme activity which suggested the specific requirement for ATP.

Genetic structure of landraces in foxtail millet (Setaria italica (L.) P. Beauv.) revealed with transposon display and interpretation to crop evolution of foxtail millet.
Although the origin and domestication process of foxtail millet (Setaria italica subsp. italica (L.) P. Beauv.) has been studied by several groups, the issue is still ambiguous. It is essential to resolve this issue by studying a large number of accessions with sufficient markers covering the entire genome. Genetic structures were analyzed by transposon display (TD) using 425 accessions of foxt...
متن کاملKinetics and Energetics of Light-driven Chloroplast Glutamine Synthesis.
Chloroplasts contain the enzyme glutamine synthetase. Formation of glutamine by isolated chloroplasts is light-dependent and requires an intact outer envelope. Addition of exogenous glutamic acid, as well as nitrogen donors such as nitrite or ammonium, stimulate the synthesis of this amide. Photosynthetic generation of ATP satisfies the light requirement of glutamine synthesis. The process is s...

The diploid C4 plant foxtail millet (Setaria italica L. Beauv.) is an important crop in many parts of Africa and Asia for the vast consumption of its grain and ability to grow in harsh environments, but remains understudied in terms of complete genomic architecture. To date, there have been only two genome assembly and annotation efforts with neither assembly reaching over 86% of the estimated ...
