Catalog No.：112P29
Brand：HongTide（上海鴻肽生物）
Description：Extracellular Death Factor是對稱的線性的五肽,其氨基酸序列為H-Asn-Asn-Trp-Asn-Asn-OH(NNWNN) 。 每個EDF的5個氨基酸的對稱分布，而且肽鏈末端的天冬酰胺對于mazEF（細菌的一種染色體）介導的殺傷活性非常重要，EDF是唯一可以啟動mazEF介導的細胞死亡的單獨的信號分子。EDF是目前發(fā)現(xiàn)的唯一參與大腸桿菌群體感應的單獨信號分子，而且EDF也是與革蘭陽性菌群體感應肽有關(guān)的一種特殊類型的分子 。
Extracellar Death Factor is a symmetrical linear pentapeptide with an amino acid sequence of H-Asn Asn Trp Asn Asn OH (NNWNN). The symmetrical distribution of 5 amino acids in each EDF, and the asparagine at the end of the peptide chain is crucial for mazEF (a type of chromosome in bacteria) mediated killing activity. EDF is the only single signaling molecule that can initiate mazEF mediated cell death. EDF is currently the only single signaling molecule found to be involved in quorum sensing in Escherichia coli, and it is also a special type of molecule related to gram-positive bacterial quorum sensing peptides.
