The Hexose-Proton Cotransport System of Chlorella
The proton concentration in the medium affects the maximal velocity of sugar uptake with a K(m) of 0.3 mM (high affinity uptake). By decreasing the proton concentration a decrease in high affinity sugar uptake is observed, in parallel the activity of a low affinity uptake system (K(m) of 50 mM) rises. Both systems add up to 100%. The existence of the carrier in two conformational states (proton...
متن کاملChlorophyll-Protein Complexes of Chlorella fusca
Chlorella, Chlorophyll-Protein Complexes, Polyacrylamide-Gel Electrophoresis, Standard Curves for Characterization of Chlorophyll Proteins Chlorophyll-protein complexes from thylakoids of the normal type and two mutants of Chlorella fusca were separated using sodium dodecyl sulfate acrylamide gel electrophoresis (PAGE). The properties of the chlorophyll-protein complexes of the three strains of...
متن کاملEssential Sulfhydryl Group in the Transport-catalyzing Protein of the Hexose-Proton Cotransport System of Chlorella.
The polyene antibiotic nystatin transforms the sugar-proton contransport system of Chlorella to a mere facilitated diffusion system. This experimental condition was used to test the sugar-translocating unit of the active uptake system for possible essential sulfhydryl groups. It could be shown that the catalyzed translocation of sugar is sensitive to the sulfhydryl-reactive compound N-ethylmale...

متن کاملSulfate Transport in Normal and S-Deprived Chlorella fusca
Cation Stimulation, Chlorella fusca, Green Alga, Multiphasic Uptake, Sulfate Analogues, Sulfate Starvation Sulfate uptake into the unicellular green alga Chlorella fusca Shihira et Krauss strain 211-8 b was described as a pH-, temperatureand energy-dependent process. Transport followed triphasic kinetics with /^-values of 1.3 x 10-5, 3.9 x 105 and 2.8 x 10 4 m . The Hill plot showed coeffi cie...
