Sn-Glycerol-3-phosphate is a Product of Starch Degradation in Isolated Chloroplasts from Chlamydomonas reinhardii
نویسندگان
چکیده
Sn-glycerol-3-phosphate accumulates during starch catabolism by intact isolated chloroplasts from Chlam ydom onas reinhardii in the dark. Further products detected mainly were 3-phosphoglyceric acid and triose phosphates with a ratio between 3-phosphoglyceric acid, sn-glycerol-3phosphate and triose phosphates of 1 .0 :0 .9 :0 .2 . The production of sn-glycerol-3-phosphate by a plastidic glycerol-3-phosphate dehydrogenase provides a reasonable mechanism for regenerating reducing equivalents during continuous starch breakdown in the chloroplast of the alga C. reinhardii.

Hydrogenase-Mediated Activities in Isolated Chloroplasts of Chlamydomonas reinhardii.
Isolated intact chloroplasts of Chlamydomonas reinhardii were found to catalyze photoreduction of CO(2) in the presence of 3-(3,4-dichlorophenyl)-1,1-dimethylurea when adapted under an atmosphere of H(2) demonstrating the association of a hydrogenase and anaerobic adaptation system with these plastids. The specific activity of photoreduction was approximately one third that detected in cells an...
متن کاملStarch degradation in chloroplasts isolated from C3 or CAM (crassulacean acid metabolism)-induced Mesembryanthemum crystallinum L.
C3 or crassulacean acid metabolism (CAM)-induced Mesembryanthemum crystallinum plants perform nocturnal starch degradation which is linear with time. To analyse the composition of metabolites released by isolated leaf chloroplasts during starch degradation we developed a protocol for the purification of starch-containing plastids. Isolated chloroplasts from C3 or CAM-induced M. crystallinum pla...

متن کاملPhysiological rates of starch breakdown in isolated intact spinach chloroplasts.
Starch breakdown with rates above 10 muatom carbon per mg chlorophyll per hour has been monitored in spinach chloroplasts and compares favorably with the rates in whole leaves. Intact starch-loaded chloroplasts were prepared from protoplasts to avoid rupture during mechanical homogenization and rapid centrifugation. Particular attention was paid to the identification of all the products of star...
متن کاملControl of Fatty Acid Incorporation into Chloroplast Lipids in vitro
1. In isolated chloroplasts which are provided with essential exogenous substrates for glycerolipid biosynthesis (sn-G3P and UDPgal) the incorporation o f fatty acids into lipids shows the same pH dependence as the fatty acid synthesis itself with a stromal pH optimum close to 8.5. 2. Furthermore high rates o f glycerolipid biosynthesis appear to be accom panied by a preferred oleate incorporat...
