  1. Mutations of the glucose-pts in sublancin-resistant B. subtilis 168 ΔSPΒ

    Gancayco, Marc RyanUniversity of Illinois at Urbana-Champaign2018

    … the deletion of and mutations in the glucose phosphotransferase system confer resistance to sublancin. In this work we add to this knowledge by generating new sublancin-resistant mutants in B. subtilis 168 ΔSPβ. The mutations found support previous findings but also demonstrate the need to …

    Kristich, Christopher JamesUniversity of Illinois at Urbana-Champaign2015

    … 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, …

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 …

  7. Structure and function of enzyme I of the PTS

    Brokx, Stephen JohnUniversity of Saskatchewan2000

    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. …
