+ | <p>The antigen 85 proteins (FbpA, FbpB, FbpC) are responsible for the high affinity of mycobacteria for fibronectin, a large adhesive glycoprotein, which facilitates the attachment of M.tuberculosis to murine alveolar macrophages (AMs). They also help to maintain the integrity of the cell wall by catalyzing the transfer of mycolic acids to cell wall arabinogalactan and through the synthesis of alpha,alpha-trehalose dimycolate (TDM, cord factor). They catalyze the transfer of a mycoloyl residue from one molecule of alpha,alpha-trehalose monomycolate (TMM) to another TMM, leading to the formation of TDM. </p> | ||

+ | <p>Protective antigen (PA) is the central component of the three-part protein toxin secreted by Bacillus anthracis, the organism responsible for anthrax. Homologues of PA have been found in several spore-forming Gram-positive bacteria, and share the ability to translocate toxic enzymes into the host cytosol.The PA monomer is organised mainly into antiparallel beta-sheets and has four domains: an N-terminal domain (domain 1) containing two calcium ions and the cleavage site for activating proteases; a heptamerisation domain (domain 2) containing a large flexible loop implicated in membrane insertion; a small domain of unknown function (domain 3); and a carboxy-terminal receptor-binding domain (domain 4) [PMID: 9039918]. | ||
+ | This entry represents domain 4 of PA, which has an immunoglobulin-like fold. Domain 4 plays a key role in cellular receptor recognition, as well as in pH-dependent pore formation[PMID: 19722284]. </p> | ||
