2.7.1.207 | 4-azidophenyl-beta-D-galactoside |
irradiation of a reaction mixture containing 0.25 mM of photoactivatable 4-azidophenyl-beta-D-galactopyranoside and enzyme with UV light at 254 nm for 3 min causes approximately 90% loss of enzyme activity. When the photoinactivation experiments are carried out in the presence of 1 mM lactose, the loss of enzyme activity is significantly slowed |

substrates of the phosphotransferase system inhibit uptake of lactose. This inhibition is reversed by intravesicular (but not extravesicular) phosphoenolpyruvate. lactose uptake is also inhibited by enzyme IIIGlc preparations that are shocked into the vesicles, and this inhibition is reversed by phosphoenolpyruvate. Enzyme I and HPr neither inhibit nor stimulate lactose uptake |

2.7.1.207 | phosphotransferase protein IIAGlc |
protein IIAGlc binding inhibits conformational dynamics of the enzyme and decreases binding affinity for sugar |
