Components of bacterial cell walls
Fimbriae (sometimes called "attachment pili") are protein tubes that extend out from the outer membrane in many members of the Pseudomonadota. They are generally short in length and present in high numbers about the entire bacterial cell surface. Fimbriae usually function to facilitate the attachment of a bacterium to a surface (e.g. to form a biofilm) or to other cells (e.g. animal cells during pathogenesis). A few organisms (e.g. Myxococcus) use fimbriae for motility to … WebNov 25, 2024 · Cell wall is composed of two polymers, one consisting of saccharide subunits and the other consisting of amino acid subunits. Thus a bacterial cell wall is glycopeptide which is also known as peptidoglycan. The saccharide component of the cell wall has alternating repeating units of two amino sugars related to glucose.
