Homology modeling of Ferredoxin-nitrite reductase from Arabidopsis thaliana
UNLABELLED Nitrogen is one of the major growth-limiting nutrients for plants: The main source of nitrogen in most of the higher plants is nitrate taken up through roots. Nitrate can be reduced both in the chloroplasts (photosynthetic tissues) and in proplastes (nonphotosynthetic tissues) such as roots. Ferredoxin-nitrite reductase (NiR) catalyses the reduction of nitrite to ammonium in the seco...
متن کاملMetabolic Interactions between Spinach Leaf Nitrite Reductase and Ferredoxin-NADP Reductase: Competition for Reduced Ferredoxin.
Steady state rates of NADP reduction decline upon commencement of nitrite reduction in reconstituted chloroplast preparations. Similarly, steady state rates of nitrite reduction are lower, but not zero, during concurrent NADP reduction. These results imply that competition for substrate occurs and suggest that nitrite reduction can successfully compete for reduced ferredoxin, even at high rates...
متن کاملInteractions between spinach ferredoxin-nitrite reductase and its substrates. Evidence for the specificity of ferredoxin.
Reduced ferredoxin can serve as electron donor in the 6-electron reduction of nitrite to ammonia catalyzed by spinach nitrite reductase. We have examined interactions between nitrite reductase and its substrates, ferredoxin and nitrite, with emphasis upon protein-protein interactions between ferredoxin and nitrite reductase. Ferredoxin, of the proteins tested, is the most effective in retarding...
متن کاملComposition of the ferredoxin-nitrite reductase from the cyanobacterium Phormidium laminosum.
Kidneys flush-stored with M C were compared with those in U W for 2 4 h and 48 h. At both 24 h and 48 h of storage, UW-stored organs produced si nificantly more glucose than those in MC. T h e uptake of "!I-PAH did not differ significantly between the two solutions. U W was subsequently modified, replacing raffinose with mannitol (solution A), lactobionate with citric acid (solution B), and sod...
متن کاملThree-Dimensional Structure of Arabidopsis thaliana Lipase Predicted by Homology Modeling Method
Triacylglycerol lipases have been thoroughly characterized in mammals and microorganisms. By contrast, very little is known about plant lipases. In this investigation, a homology model of Arabidopsis thaliana lipase (NP_179126) was constructed using a human gastric lipase (PDB ID: 1HLG), as a template for model building. This model was then assessed for stereochemical quality and side chain env...
