Brand：HongTide（上海鴻肽生物）
Description：短桿菌肽A是由短芽孢桿菌產(chǎn)生的一種抗生素，為線狀十五肽，N端甲?；忾]氨基，C端是醛基。短桿菌肽A能夠殺死某些微生物．兩個(gè)短桿菌肽A分子從膜兩側(cè)相對(duì)插入可形成穿膜通道，提高生物膜對(duì)某些一價(jià)陽(yáng)離子的通透性，使這些物質(zhì)順濃度梯度通過(guò)細(xì)胞膜，不過(guò)短桿菌肽A并不顯著提高運(yùn)輸速度。研究顯示短桿菌肽A能抑制T7噬菌體DNA的轉(zhuǎn)錄，抑制膜結(jié)合的表皮腺苷酸三磷酸酶活性和體外阻抑人淋巴細(xì)胞轉(zhuǎn)化。在大鼠動(dòng)物模型中能延長(zhǎng)心臟移植存活率。
Gramicidin A is an antibiotic produced by Bacillus subtilis, which is a linear pentapeptide with N-terminal formylation blocking amino group and C-terminal aldehyde group. Short peptide A can kill certain microorganisms. Two short peptide A molecules can be inserted relative to each other from both sides of the membrane to form transmembrane channels, improving the permeability of the biofilm to certain monovalent cations, allowing these substances to pass through the cell membrane in a concentration gradient. However, short peptide A does not significantly improve transportation speed. Studies have shown that short peptide A can inhibit the transcription of T7 bacteriophage DNA, inhibit membrane bound epidermal adenosine triphosphatase activity, and inhibit human lymphocyte transformation in vitro. It can prolong the survival rate of heart transplantation in rat animal models.
