A constitutive peptide lactonase from Actinoplanes missouriensis hydrolyzed echinomycin, stendomycin, thiostrepton, vernamycin B, staphylomycin S, and etamycin. An induced lactonase hydrolyzed actinomycin but not the other peptide lactones.
Histidine kinases are common sensory proteins used to detect environmental changes in bacteria. They respond specific stimuli via a signal-input domain and alter gene expression through cognate response regulator. The modulation/control of transcriptional regulation cyanobacteria is important reinforce the production useful target compounds photosynthesis without altering growth profiles. For i...
BACKGROUND AND OBJECTIVES There is increasing emergence of multidrug resistant Pseudomonas aeruginosa (MDRPA) strains and drug resistance is positively-correlated with biofilm-forming ability. Since about 10% of P. aeruginosa genome is controlled by quorum sensing (QS), alteration in its antibiotic susceptibility by targeting QS was the focus of the present study. MATERIALS AND METHODS One da...
Rett syndrome (RTT) and autism spectrum disorders (ASDs) are not merely expression of brain dysfunction but also reflect the perturbation of physiological/metabolic homeostasis. Accordingly, both disorders appear to be associated with increased vulnerability to toxicants produced by redox imbalance, inflammation, and pollution, and impairment of systemic-detoxifying agents could play a role in ...
PURPOSE Thrombosis of native arteriovenous (AV) fistula is an important cause of complications in hemodialysis (HD) patients. The purpose of this study was to investigate the usefulness of measuring circulating fibroblast growth factor-23 (FGF-23) level and paraoxonase-1 (PON1) lactonase activity as potential predictors of native AV fistula thrombosis in chronic HD patients. METHODS This stud...
