Evolution of Plant Sucrose Uptake Transporters
In angiosperms, sucrose uptake transporters (SUTs) have important functions especially in vascular tissue. Here we explore the evolutionary origins of SUTs by analysis of angiosperm SUTs and homologous transporters in a vascular early land plant, Selaginella moellendorffii, and a non-vascular plant, the bryophyte Physcomitrella patens, the charophyte algae Chlorokybus atmosphyticus, several red...
متن کاملSucrose- and H+-Dependent Charge Movements Associated with the Gating of Sucrose Transporter ZmSUT1
BACKGROUND In contrast to man the majority of higher plants use sucrose as mobile carbohydrate. Accordingly proton-driven sucrose transporters are crucial for cell-to-cell and long-distance distribution within the plant body. Generally very negative plant membrane potentials and the ability to accumulate sucrose quantities of more than 1 M document that plants must have evolved transporters wit...
متن کاملZinc- and bicarbonate-dependent ZIP8 transporter mediates selenite uptake
Selenite (HSeO3-) is a monovalent anion of the essential trace element and micronutrient selenium (Se). In therapeutic concentrations, HSeO3- has been studied for treating certain cancers, serious inflammatory disorders, and septic shock. Little is known, however, about HSeO3- uptake into mammalian cells; until now, no mammalian HSeO3- uptake transporter has been identified. The ubiquitous mamm...
متن کاملAnalysis of the transport activity of barley sucrose transporter HvSUT1.
Localization studies indicate that barley (Hordeum vulgare) sucrose transporter HvSUT1 functions in sucrose uptake into seeds during grain filling. To further understand the physiological function of HvSUT1, we have expressed the HvSUT1 cDNA in Xenopus laevis oocytes and analyzed the transport activity by two-electrode voltage clamping. Consistent with a H(+)-coupled transport mechanism, sucros...
متن کاملNPC1L1: evolution from pharmacological target to physiological sterol transporter.
Niemann-Pick C1-like 1 protein (NPC1L1) was recently shown to be the molecular target of the cholesterol absorption inhibitor class of drugs, of which ezetimibe is the first widely used member. Since its discovery, NPC1L1 has also been shown to play a focal physiological role in intestinal absorption of sterols, including plant sterols and cholesterol. Evidence in support of this new metabolic ...
