Primary Substrate

To illustrate the emerging class of anion exchange proteins in bacteria, this article discusses the biochemical and physiological properties of phosphate (Pi)-linked antiporters that accept glucose 6-phosphate (G6P) as their primary substrate. These systems have a bifunctional active site that binds a pair of negative charges, whether presented as a single divalent anion or a pair of monovalent substrates. Exchange stoichiometry therefore .moves between the limits of 2:1 and 2:2 according to the ratio of mono- and divalent substrates at either membrane surface. This predicts an interesting reaction sequence in vivo because internal pH is more alkaline than external pH; one expects an asymmetric exchange as a pair of monovalent G6P anions moves against a single divalent G6P, and in this way an otherwise futile selfexchange of G6P can result in a net inward flux driven (indirectly) by the pH gradient. Despite their biochemical complexity, at a molecular level the Pi-linked antiporters resemble other secondary carriers. Indeed, the current listing of nearly two dozen such proteins suggests a structural theme in which the minimal functional unit has two sets of six transmembrane alpha helices separated by a central hydrophilic loop. Presently described examples show that this topology can derive from either a single protein or from pairs of identical subunits. The finding of this common structure makes it possible to begin building more detailed structural models that have more general implications.

Abstract The metals Mn, Mg, Co, Cu, and Zn were separated by using an anion exchange resin column and progressively less concentrated IIC1 solution as eluting agent. The position of Mg on an anion exchange resin, not previously reported in the literature, was determined. It has been shown that by using two different ion exchange resin columns, simple hydrochloric acid solutions as eluants, and polarographic or flame photometric determinations, 12 metals can be separately estimated in an aqueous solution containing about 100 /μg of each. It is recommended that the study of ion exchange resin separation of metals found in plants be continued.

Unique BiVO4/Bi2S3 cruciate hollow heterostructures are successfully constructed via anion exchange reactions using cruciate BiVO4 as templates and precursors. The hollow heterostructures exhibit excellent enhanced photocurrent response and photocatalytic activity for reduction of Cr6+ under visible-light illumination.
