N-酰基高丝氨酸内酯类化合物(N-acyl-homoserinelactones，AHLs)是革兰氏阴性细菌群体感应系统中最典型的一类信号分子。研究表明，许多革兰氏阴性细菌都靠分泌AHLs进行交流和协调群体行为。由AHLs介导的细菌群体感应系统参与许多生物学功能的调控，如毒素的产生、生物膜的形成、生物发光、抗生素形成等。今天，就与小普一起...

The aim of this research was to detect the N-acyl homoserine lactones (AHLs) production and QseB/C gene of Aeromonas hydrophila. We analyzed the potentials of these isolates of Aeromonas hydrophila in causing biofilm formation, hemolysis, protease, and lipase. The antibiotic susceptibility of the...
在不同种类的细菌中所分泌的ai也会有所不同,如革兰氏阴性菌会分泌n-酰基-高丝氨酸内酯(n-acyl-homoserine lactones,ahls),而革兰氏阳性菌会分泌寡肽作为自诱导物。群体感应机制的调控作用与自诱导物的分泌以及自诱导物与其他信号分子交互作用密切相关。如环二鸟苷酸(bis-(3'-5')-cyclic dimeric guanosinemonophos...
N-Acyl-L-homoserine lactones (AHLs) are signal molecules that are synthesized in nature by Gram-negative bacteria. They allow communication between bacteria (quorum sensing) and between microorganisms and their eukaryotic host cells (inter-kingdom signalling). However, very little is known about the...
N-Acyl-l-homoserine lactones (AHLs) are a large family of signaling molecules in “quorum sensing” communication. This mechanism is present in a number of bacterial physiological phenomena, including pathogenic phenomena. In this study, we described a simple and accessible way to detect, annotate...
A method for the analysis of N -acyl- L -homoserine lactones (AHLs) with micellar electrokinetic chromatography coupled to electrospray ionization-ion trap mass spectrometry, combining the flexibility of capillary electrophoresis with the unmatched structural information provided by mass spectrometry is ...
N-酰基高丝氨酸内酯(N—acyl.homoserinelactones,AHLs)是许多革兰氏阴性 茵群体感应系统中的信号分子,能够调节许多动植物病原菌致病基因的表达。N.酰 基高丝氨酸内酯酶可以水解AHLs的内酯键,使信号分子失去活性,从而降低致病 菌产生的危害。本实验从苏云金芽胞杆菌菌株LLBl5中克隆出N一酰基高丝氨酸内 ...
