WebJul 11, 2013 · LuxI-type synthases are considered as members of the Gcn5-related N -acetyltransferase superfamily ( 6 ), and yet they catalyze a unique reaction unlike other characterized enzymes in this superfamily ( 7 ). Acyl-HSL synthases are unique enzymes, not present in Eukarya, and they are essential for quorum sensing. WebFeb 12, 2024 · Our phylogenetic and motif analysis of the LuxI acyl-HSL synthase family indicates that the acyl-CoA-utilizing enzymes evolved from an acyl-ACP-utilizing ancestor.

WebSep 1, 2015 · Many proteobacteria possess so-called LuxR orphans or solos, meaning LuxR-type receptors that are not paired with a LuxI-type synthase. LuxR solos can either exist in HSL-communicating bacteria, e.g. QscR of Pseudomonas aeruginosa sensing endogenous acyl-HSL , or in those that do not synthesize these molecules, such as SdiA of Escherichia … WebMay 16, 2024 · A LuxI/LuxR homolog consisting of a conserved AHL synthase gene ( luxI) and a transcriptional regulator gene ( luxR) was identified in the strain. Two in-frame deletion mutants of luxI and luxR, ∆ luxI and ∆ luxR, were constructed to explore their QS signaling function in P. fluorescens.
WebAug 23, 2024 · One class of these chemical signals, known as homoserine lactones (HSLs), is produced by a family of synthase enzymes called LuxI-like proteins [ 4 – 6 ]. HSLs have traditionally been referred to as N-acyl homoserine lactones (AHLs). However synthases also produce non-acyl chain homoserine lactones, so in this report we use the general … WebHomologs of both the HSL synthase (LuxI-type synthase) and HSL receptor (LuxR-type receptor) are found in many Gram-negative bacteria and regulate quorum sensing in …
