Magnesium transport in Salmonella typhimurium. Regulation of mgtA and mgtB expression.
Salmonella typhimurium contains three distinct transport systems (CorA, MgtA, and MgtB) that move Mg2+ across the cytoplasmic membrane. Mutant strains containing only one of these three systems haveExpand

Thioltransferase is a specific glutathionyl mixed disulfide oxidoreductase.
To study the substrate specificity and mechanism of thioltransferase (TTase) catalysis, we have used 14C- and 35S-radiolabeled mixed disulfides of cysteine and glutathione (GSH) with variousExpand

Amyloid beta protein (A beta) in Alzheimer's disease brain. Biochemical and immunocytochemical analysis with antibodies specific for forms ending at A beta 40 or A beta 42(43).
Biochemical and immunocytochemical analyses were performed to evaluate the composition of the amyloid beta protein (A beta) deposited in the brains of patients with Alzheimer's disease (AD). ToExpand

Thioltransferase in human red blood cells: kinetics and equilibrium.
Thioltransferase from human red blood cells (HRBC TTase), coupled to GSSG reductase, catalyzed glutathione (GSH)-dependent reduction of prototype substrates hydroxyethyl disulfide (HEDS) and sodiumExpand

The glucose transporter of the human brain and blood‐brain barrier
We identified and characterized the glucose transporter in the human cerebral cortex, cerebral microvessels, and choroid plexus by specific D‐glucose‐displaceable [3H]cytochalasin B binding. TheExpand

The primary structure and properties of thioltransferase (glutaredoxin) from human red blood cells
Thioltransferase (glutaredoxin) was purified from human red blood cells essentially as described previously (Mieyal JJ et al., 1991a, Biochemistry 30:6088–6097). The primary sequence of the HPLC‐pureExpand
