Chemotactic Sensory Transduction in Bacillus Subtilis: A New Enzyme and a New Pathway
… substrates of the phosphoenolpyruvate-dependent-phosphotransferase system (PTS) in E. coli is accomplished using a chemoreceptor-independent signaling circuit in which phosphoryl flux through the PTS is monitored and used directly to modulate the activity of the chemotactic kinase. In contrast, …

Biochemistry and regulation of CheA in Bacillus subtilis chemotaxis
… to date. Studies on the enteric chemotaxis system revealed that taxis toward certain sugars is mediated solely through a separate phosphoenolpyruvate-dependent phosphotransferase system (PTS), involved in sugar transport. In B. subtilis, we have determined that taxis toward PTS carbohydrates …

Microbial glucosinolate metabolism: Characterization of Enterococcus faecalis XL1 and functional analysis of a GH4 enzyme
… analyses identified multiple β-glucoside phosphotransferase system (PTS) transporters and glycoside hydrolases (GHs) responsive to sinigrin, with a GH4 enzyme Ef5510, showing the strongest induction. Functional studies revealed that Ef5510 is an NAD+/Mn2+-dependent hydrolase, and the …

Structure and function of enzyme I of the PTS
The phosphoenolpyruvate: sugar phosphotransferase system (PTS) is responsible for the uptake and concomitant phosphorylation of many sugars in several species of bacteria. The first step of the PTS involves the phosphorylation of histidine containing phosphocarrier protein (HPr) by enzyme I (E.C. …

Examination of Glucose Transport in Clostridium Beijerinckii NCIMB 8052 and the Solvent Hyper-Producing Mutant BA101
… of a phosphoenolpyruvate (PEP) dependent phosphotransferase system (PTS) associated with cell-free extracts of C. beijerinckii BA101 by glucose phosphorylation by PEP. The PTS activity associated with C. beijerinckii BA101 was 50% of that observed for C. beijerinckii 8052. C. beijerinckii …

Functional Characterization of Atxa, The Bacillus Anthracis Virulence Regulator
… associated with phosphoenolpyruvate: sugar phosphotransferase system (PTS) regulation. These PTS-regulated domains, PRD1 and PRD2, are within the central amino acid sequence. Specific histidines in the PRDs serve as sites of phosphorylation (H199 and H379). Phosphorylation of H199 increases …

A drinking water microbiome from source to tap: Community diversity, functionality, and microbial interaction
… space” in selected stages of drinking water systems. However, it is important to ask additional questions that include but are not limited to “what are they doing?”, “why are they there?” and more critically “who is doing what?”, and “what are the interrelationships among them, and between …

Carbon Catabolism in <i>Bacillus subtilis</i>: Global and Molecular Views on the Control of Gene Expression
… erfolgt über das Phosphoenolpyruvat:Zucker Phosphotransferase System (PTS), welches durch das ptsGHI-Operon kodiert wird. Die Expression dieses Operons sowie die Expression einiger weiterer zuckerspezifischer Permeasen werden durch transkriptionelle Antitermination kontrolliert. Hierbei kann …

Characterisation of glycosidase enzymes of wine lactic acid bacteria
… in what, most likely, seemed operons of the phosphotransferase system (PTS) of the carbohydrate catabolism. Two of these enzymes were in the same operon, which showed a higher PTS structure than the other. In fact there was a gene codifying for putative a transcriptional regulator, most …
