Pathogenic bacteria employ an array of protein molecules and/ or secondary metabolites as mediators of pathogenicity in human, animal, and plant hosts. Normally, while bacterial molecules like lipopolysaccharides, capsular polysaccharides, peptidoglycans, and lipoproteins serve as pathogenassociated molecular patterns to initiate interactions with all the host, in addition they activate the host innate immune technique [1,2]. To evade host defense systems, pathogens straight inject bacterial proteins, referred to as effectors, into the cytosolic compartment of host cells by means of many secretion systems [3], which happen to be effectively characterized in plant immune responses [1]. Effectors play essential roles in pathogenesis by disturbing the metabolism of host cells through quite a few diverse techniques [3]. Furthermore to these lately characterized processes, bacteria have also been shown to synthesize and secrete toxic low molecular weight chemical substances, collectively known as toxins, as virulence aspects [6]. The modes of action, that are one of a kind to every toxin, show excellent diversity in host cells and variety from gene regulation towards the manage of ion channel activity [6,7]. Structural and singlemolecule studies of toxins in complexes with targetproteins have offered molecular insights into the functional roles of those toxins [8,9]. In current years, it has turn into evident that the expression of genes involved within the synthesis and secretion of toxins is regulated in the degree of transcription by quorum sensing, the central mechanism for bacterial intercellular signaling that utilizes diffusible tiny chemical compounds as a signal [10]. This basic theme is applicable towards the phytopathogenic bacterium Burkholderia glumae BGR1, that is responsible for rice grain rot and wilt in Phenmedipham In Vitro several field crops. B. glumae produces toxoflavin (Figure 1A) [11], which acts as a essential factor in this illness, possibly by producing superoxide and hydrogen peroxide [12,13]. In truth, the synthesis and transport of toxoflavin in B. glumae were shown to become coordinately regulated by quorum sensing signals [14]. Thus, interference of quorum sensing known as quorum quenching has been recommended as the antivirulence approach, in which Nacylhomoserine lactones (AHLs), the quorum sensing signals made in many Gramnegative bacteria, have been degraded [15]. For example, lactonases produced by some Bacillus spp. are known to hydrolyze the lactone bond in the homoserine ring of AHLs, and transgenic plants expressing Bacillus AHL lactonase showedPLoS A single | www.plosone.orgStructure of ToxoflavinDegrading EnzymeFigure 1.
