Bacterial enzymes and membranes in oral bacteria

Bacterial enzymes and membranes in oral bacteria comprise a wide variety of membrane-bound and secreted proteins essential for metabolism, survival, biofilm formation, and pathogenicity in the oral cavity. Key examples include outer membrane vesicles (OMVs) released by pathogenic bacteria such as Porphyromonas gingivalis and Treponema denticola; these vesicles carry virulence factors and contribute to disease progression in periodontitis and systemic diseases. Membrane proteins include integral, peripheral, and lipid-anchored proteins, some functioning as transporters, signal transducers, or enzymes involved in energy metabolism. Targeting these structures and their associated enzymes with antimicrobials or engineered therapeutics represents a major avenue for the treatment and prevention of oral microbial diseases, though the term itself denotes a large molecular class rather than a singular, well-defined target[1][3][4][5][6][7][9].
