Periplasmically

Periplasmically refers to something occurring within or related to the periplasm. The periplasm is a compartment found in Gram-negative bacteria and some Archaea. It is located between the inner and outer membranes of the cell envelope. This space contains various proteins, enzymes, and other molecules that are essential for cellular functions such as nutrient uptake, cell wall synthesis, and signal transduction. The term "periplasmically" would thus describe the location or movement of substances within this specific compartment. For example, certain proteins are secreted into the periplasm, or biochemical reactions may take place periplasmically. Understanding the periplasm and processes occurring periplasmically is crucial for comprehending the unique biology of Gram-negative bacteria, including their interactions with the environment and their susceptibility to antibiotics that target this region. The composition and function of the periplasm can vary among different species.
