The periplasmic space is quizlet

Webb17 jan. 2024 · Abstract. Gram-negative bacteria are surrounded by two membrane bilayers separated by a space termed the periplasm. The periplasm is a multipurpose compartment separate from the cytoplasm whose distinct reducing environment allows more efficient and diverse mechanisms of protein oxidation, folding, and quality control. WebbThe 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 cryoelectron microscopy, it has been found that a much smaller periplasmic space is also present in gram-positive bacteria.

WebbAbstract. The β-barrel outer membrane proteins (OMPs) are integral membrane proteins that reside in the outer membrane of Gram-negative bacteria and perform a diverse range of biological functions. Synthesized in the cytoplasm, OMPs must be transported across the inner membrane and through the periplasmic space before they are assembled in … WebbThe periplasmic space is the space seen between the plasma membrane and the outer membrane in the gram-negative bacteria. A very small periplasmic space between the plasma membrane and the peptidoglycan layer ( cell wall) may be observed in the gram-positive bacteria (Zuber et al., 2006).
