GUP1 and its close homologue GUP2, encoding multimembrane-spanning proteins involved in active glycerol uptake in Saccharomyces cerevisiae.
Many yeast species can utilize glycerol, both as a sole carbon source and as an osmolyte. In Saccharomyces cerevisiae, physiological studies have previously shown the presence of an active uptakeExpand

Fps1p channel is the mediator of the major part of glycerol passive diffusion in Saccharomyces cerevisiae: artefacts and re-definitions.
Glycerol has been shown to cross the plasma membrane of Saccharomyces cerevisiae through (1) a H(+)/symport detected in cells grown on non-fermentable carbon sources, (2) the constitutively expressedExpand

Characteristics of Fps1-dependent and -independent glycerol transport in Saccharomyces cerevisiae.
Eadie-Hofstee plots of glycerol uptake in wild-type Saccharomyces cerevisiae W303-1A grown on glucose showed the presence of both saturable transport and simple diffusion, whereas an fps1delta mutantExpand

Characterization of a glycerol/H+ symport in the halotolerant yeast Pichia sorbitophila.
Pichia sorbitophila is a halotolerant yeast capable of surviving to extracellular NaCl concentrations up to 4 M in mineral medium when glucose or glycerol are the only carbon and energy sources.Expand

Biodiversity of Angola
Angola possesses an unusually rich diversity of ecosystems and species, but this natural wealth is poorly documented when compared with other countries in the region. Both colonial history andExpand

New insights on glycerol transport in Saccharomyces cerevisiae
Previous studies evidenced in Saccharomyces cerevisiae the activity of a H+/glycerol symport, derepressed by growth on non‐fermentable carbon sources, later associated with GUP1 and GUP2 genes. ItExpand

Isolation and characterisation of mutants from the halotolerant yeast Pichia sorbitophila defective in H+/glycerol symport activity.
Pichia sorbitophila, a yeast species that is highly resistant to osmotic stress in general and to salt stress in particular, was subjected to a mutagenesis strategy in order to obtain mutantsExpand

Matriclans shape populations: Insights from the Angolan Namib Desert into the maternal genetic history of southern Africa.
OBJECTIVES Southern Angola is a poorly studied region, inhabited by populations that have been associated with different migratory movements into southern Africa. Apart from Kx'a-speaking SanExpand
