    Nucleoside polyphosphates mediate metabolic changes in prokaryotes, enabling adaptation to nutrient availability and development. This review details their role in the stringent response and broader cellular regulation.

    Area of Science:

    • Microbiology
    • Molecular Biology
    • Biochemistry

    Context:

    • Prokaryotes possess sophisticated regulatory systems to adapt metabolism to environmental changes, such as nutrient availability.
    • These systems allow for growth reduction and the initiation of developmental processes.
    • Nucleoside polyphosphates act as key signaling molecules in these adaptive responses.

    Purpose:

    • To review the characteristics, occurrence, and metabolism of nucleoside polyphosphates.
    • To elucidate the role of nucleoside polyphosphates as mediators of coordinated metabolic alterations in prokaryotes.
    • To explore the pleiotropic effects of these molecules on various cellular processes.

    Summary:

    • This review focuses on nucleoside polyphosphates, which are crucial mediators of metabolic adjustments in prokaryotes.
