The where, when, and how of organella acidification by the yeast vacuolar H(super +)-ATPase

Article Abstract:

All eukaryotic cells contain multiple acidic organelles, and vacuolar proton-translocating ATpase (V-ATPases) are central players in organella acidification. These mechanisms allow cells both to regulate the pHs of different compartments and to respond to changing extracellular conditions while the Saccharomyces cerevisiae V-ATPase has emerged as an important model for V-ATPase structure and function in all eukaryotic cells

Eukaryotic MCM proteins: Beyond replication initiation

Article Abstract:

The minichromosome maintenance (MCM) protein family is composed of six related proteins that are conserved in all eukaryotes. They were first identified by generic screens in yeast and subsequently analyzed in other experimental systems using molecular and biochemical methods.

Human chromosomes, DNA replication

The acetate switch

Article Abstract:

'Acetate switch' occurs as cells deplete their environment of acetate-producing carbon sources and begin to rely on their ability to scavenge for acetate. The 'acetate switch' as it exists in selected eubacteria, archaea, and eukaryotes including humans is described.
