O le ExPortal protein secretion organelle i Streptococcus pyogenes o se anionic phospholipid-containing membrane microdomain ua faʻatamaoaigaina i Sec translocons ma postsecretion protein biogenesis factors.O le Polymyxin B e fusifusia ma faʻalavelaveina le faʻamaoni ExPortal, e mafua ai le faʻaleagaina o le tele o toxins.Ina ia maua le malamalama i mea e aʻafia ai le faʻalapotopotoga a ExPortal, na faia se suʻesuʻega faʻapitoa e filifili ai mo mutants polymyxin B-resistant faʻaalia e faʻaleleia le amio saʻo ExPortal.O le fa'asologa atoa o le genome e 25 na fa'aalia mai le tasi i le fa suiga i le genome mutant o lo'o fa'aputuina i totonu o se seti autu o 10 vaega o kenera.O le fausiaina o mutants ma tapeina taʻitasi poʻo faʻaofiina na faʻaalia ai e 7 kenera autu e tuʻuina atu le tetee ma faʻaleleia le amiosaʻo ExPortal e ala i le leiloa o galuega, ae 3 e foliga mai ona o le mauaina o galuega ma / poʻo aʻafiaga tuʻufaʻatasia.O kenera e tete'e ai e aofia ai se fa'atonu fa'aliliu o le biosynthesis o le lipid, le tele o kenera e a'afia i le mauaina o mea'ai, ma le tele o kenera e a'afia i tali fa'alavelave.E toʻalua sui o le vasega mulimuli o loʻo galulue foi o ni faʻatonuga fou o le SpeB cysteine ​​protease faalilolilo.O le suʻesuʻega o le suiga e masani ona faʻaesea, o le soloina o le nucleotide e tasi i se ala o 9 adenine soʻo totoe i le pstS, faʻapipiʻiina se vaega o le maualuga-affinity Pi transporter, o loʻo fautua mai ai o lenei faʻasologa o loʻo galue o se ki mole mole e faʻafaigofie ai le fetuunaiga o le atuatuvale.Faʻatasi, o nei faʻamatalaga o loʻo fautua mai ai le i ai o se tali faʻamaʻi membrane lea e faʻamalosia ai le faʻaleleia o le faʻamaoni ExPortal ma le tetee atu i cationic antimicrobial peptides.
