Regulation of compatible solute accumulation in bacteria.
In their natural habitats, microorganisms are often exposed to osmolality changes in the environment. The osmotic stress must be sensed and converted into an activity change of specific enzymes and transport proteins and/or it must trigger their synthesis such that the osmotic imbalance can be rapidly restored. On the basis of the available literature, we conclude that representative gram-negat...
متن کاملIntroducing ectoine as compatible solute: biosynthetic pathway, production and applications
Halophilic microorganisms cope with environmental stresses by producing and accumulating compatible solutes. Ectoine is one of the most important members of compatible solutes which have extra protective properties compared to other compatible solutes. Ectoine attracts several scientific and commercial attention because of their multiple industrial applications. This brief review presents appli...
متن کاملOsmosensing and osmoregulatory compatible solute accumulation by bacteria.
Bacteria inhabit natural and artificial environments with diverse and fluctuating osmolalities, salinities and temperatures. Many maintain cytoplasmic hydration, growth and survival most effectively by accumulating kosmotropic organic solutes (compatible solutes) when medium osmolality is high or temperature is low (above freezing). They release these solutes into their environment when the med...
متن کاملRegulation of heme biosynthesis in non-phototrophic bacteria.
The biosynthesis of tetrapyrroles like hemes and chlorophylls is essential for most living organisms. In bacteria hemes are integral parts of energy conserving electron transport chains and cofactors of various enzymes. Changes of environmental conditions usually lead to an adaption of the bacterial energy metabolism and often coincide with significant changes of cellular heme levels. This revi...
متن کاملGenome-driven investigation of compatible solute biosynthesis pathways of Pseudomonas syringae pv. syringae and their contribution to water stress tolerance.
The foliar pathogen Pseudomonas syringae pv. syringae exhibits an exceptional ability to survive on asymptomatic plants as an epiphyte. Intermittent wetting events on plants lead to osmotic and matric stresses which must be tolerated for survival as an epiphyte. In this study, we have applied bioinformatic, genetic, and biochemical approaches to address water stress tolerance in P. syringae pv....
