Dimerization is a common feature among the members of the neurotransmitter:sodium symporter (NSS) family of membrane proteins. Yet, the effect of dimerization on the mechanism of action of NSS members is not fully understood. In this study, we examined the collective dynamics of two members of the family, leucine transporter (LeuT) and dopamine transporter (DAT), to assess the significance of d...
A cDNA coding for a vitamin H (biotin) transport protein from Arabidopsis was identified by genetic complementation of a biotin uptake-deficient yeast mutant. Vitamin H transport by this protein was sensitive to the SH-group inhibitor p-chloromercuribenzene sulfonic acid (PCMBS) and to the uncoupler carbonyl cyanide-m-chlorophenylhydrazone (CCCP), suggesting an energy-dependent biotin-H+ sympor...
Single nucleotide polymorphisms (SNPs) in genes encoding or influencing renal sodium transport systems were investigated as potential predictors of blood pressure (BP) response to a thiazide diuretic. A sample of 585 adults with essential hypertension (30 to 59.9 years of age; 50% blacks; 47% women) were treated with hydrochlorothiazide for 4 weeks (25 mg daily, orally) to determine office BP r...
Hadjikoutis and Wiles draw attention to a number of circumstances in which the serum chloride and bicarbonate can be misleading. They do not mention that they will also be misleading if they are measured when hypercapnia is increasing or decreasing. An exacerbation of hypercapnia will take 4 – 6 days to raise the serum bicarbonate and lower the serum chloride to new steady levels. 1 How long it...
GABA(A) receptors form Cl(-) permeable channels that mediate the majority of fast synaptic inhibition in the brain. The K(+)/Cl(-) cotransporter KCC2 is the main mechanism by which neurons establish low intracellular Cl(-) levels, which is thought to enable GABAergic inhibitory control of neuronal activity. However, the widely used KCC2 inhibitor furosemide is nonselective with antiseizure effi...
It is found that dark reduction of photooxidized primary electron donor P870+ in reaction centres from purple anoxygenic bacteria (two non-sulphur Fe-oxidizing Rhodovulum iodosum and Rhodovulum robiginosum, Rhodobacter sphaeroides R-26 and sulphur alkaliphilic Thiorhodospira sibirica) is accelerated upon the addition of Mn2+ jointly with bicarbonate (30-75 mM). The effect is not observed if Mn2...
Rhodopirellula baltica (R. baltica) is a Planctomycete, known to have intracellular membranes. Because of its unusual cell structure and ecological significance, we have conducted comprehensive analyses of its transmembrane transport proteins. The complete proteome of R. baltica was screened against the Transporter Classification Database (TCDB) to identify recognizable integral membrane transp...
