(N-琥珀酰亚胺基氧代羰基甲基)三(2,4,6-三甲氧苯基)溴化膦
作者：德尔塔 日期：2022-01-14
N-Succinimidyloxycarbonylmethyl tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPP-Ac-OSu) is an acylating reagent, and is generally used for the selective derivatization of N-terminal a-amino group of peptide. The TMPP-acetylated peptides undergo fragmentation thereby creating a-type ions, thus obtaining sequence information becomes easier, even without the usage of automated computational approach. It can be used as a labelling reagent in liquid chromatography-coupled mass spectrometry (LC-MS/MS) of N-terminal peptides, so as to improve ionization efficiency, simplify fragmentation, and retention times, thereby leading to better separation of peptides.肽 N-末端改性试剂,用于快原子轰击 (FAB) 或基质辅助激光解吸/电离质谱 (MALDI MS) 属性 产品名称 (N-琥珀酰亚胺基氧代羰基甲基)三(2,4,6-三甲氧苯基)溴化膦

N-(β-ketocaproyl)-L-Homoserine lactone is a component of quorum regulatory sensing which is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density. This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production. Coordinated gene expression is achieved by the production, release, and detection of small diffusible signal molecules called autoinducers. The N-acylated homoserine lactones (AHLs) comprise one such class of autoinducers, each of which generally consists of a fatty acid coupled with homoserine lactone (HSL). Regulation of bacterial quorum sensing signaling systems to inhibit pathogenesis represents a new approach to antimicrobial therapy in the treatment of infectious diseases. AHLs vary in acyl group length (C4-C18), in the substitution of C3 (hydrogen, hydroxyl, or oxo group), and in the presence or absence of one or more carbon-carbon double bonds in the fatty acid chain. These differences confer signal specificity throμgh the affinity of transcriptional regulators of the LuxR family. In one of the most-studied quorum-sensing systems in gram-negative bacteria, the LuxI AHL synthase catalyzes the production of N-(β-ketocaproyl)-L-homoserine lactone utilizing S-adenosylmethionine and hexanoyl-acyl carrier protein as reaction substrates in the marine bioluminescence bacterium V. fischeri. At increased populations of the bacteria, localized higher concentrations of 3-O-C6-HSL, an endogenous ligand to transcriptional factor LuxR, leads to increased
