A substrate translocation trajectory in a cytoplasm-facing topological model of the monocarboxylate/H+ symporter Jen1p [PDF]
Previous mutational analysis of Jen1p, a Saccharomyces cerevisiae monocarboxylate/H+ symporter of the Major Facilitator Superfamily, has suggested that the consensus sequence 379NXX[S/T]HX[S/T]QD387 in transmembrane segment VII (TMS-VII) is part of the ...

Alternate Modes of Photosynthate Transport in the Alternating Generations of Physcomitrella patens
Physcomitrella patens has emerged as a model moss system to investigate the evolution of various plant characters in early land plant lineages. Yet, there is merely a disparate body of ultrastructural and physiological evidence from other mosses to draw ...

A Biological Perspective on Sorting with P Systems [PDF]
The aim of this contribution is to argue that the processes occurring in biological membranes in bacteria are also important as natural examples of communication between membranes, which, in the formal framework of P systems, leads (among other things)

Na+-dependent and Na+-independent betaine transport across the apical membrane of rat renal epithelium [PDF]
The low renal excretion of betaine indicates that the kidney efficiently reabsorbs the betaine filtered by the glomeruli but the mechanisms involved in such a process have been scarcely investigated.

Magnesium deficiency in sugar beets alters sugar partitioning and phloem loading in young mature leaves [PDF]
Magnesium deficiency has been reported to affect plant growth and biomass partitioning between root and shoot. The present work aims to identify how Mg deficiency alters carbon partitioning in sugar beet (Beta vulgaris L.) plants.

Adaptive regulation of epithelial transporters to nutrient intake is essential to decrease energy costs of their synthesis and maintenance, however such regulation is understudied. Previously we demonstrated that the transport function of the basolateral
