WebDec 24, 2024 · The periplasm space can act as reservoir for virulence factors and a dynamic flux of macromolecules representing the cell’s metabolic status and its response to environmental factors. Together, the plasma membrane and the cell wall (outer membrane, peptidoglycan layer, and periplasm) constitute the gram-negative envelope. Key Points The periplasm is a concentrated gel-like matrix in the space between the inner cytoplasmic membrane and the bacterial outer membrane called the periplasmic space in gram-negative bacteria. Using cryo-electron microscopy it has been found that a much smaller periplasmic space is also present in gram-positive bacteria.

The function of the DegP (HtrA) protein: Protease versus chaperone

WebDue to the function of the proton pump, which compartment will have a lower pH? neither; H+ transport establishes equilibrium across the membrane O the cell cytoplasm o the extracellular (periplasmic) space QUESTION 3 Select a single correct answer. What type of transport is the H+ / lactose cotransporter responsible for? WebThe DegP (or HtrA) is a highly conserved family of proteins functioning in all living organisms. It was initially identified as a protease functioning in the periplasmic space of the Gram-negative bacterial cells. It was later reported to also exhibit chaperone activity and thus has been designated as a bifunctional protein. asa duodenal
