10 Questions
The response regulator, once phosphorylated, binds to the activator to turn transcription on.
True
Porins in Gram-negative bacteria regulate the synthesis of histidine kinases.
False
Phosphatase activity removes phosphate from the response regulator at a faster rate than kinase activity.
False
OmpC is synthesized more in bacterial cells when there is low solute concentration.
False
NRII becomes dephosphorylated when excess ammonia is present in the environment.
True
Phosphorylation of NRI by PII leads to the binding of NRI to the activator binding site.
True
The dual enzymatic activity of NRII is controlled by the response regulator.
False
Ammonia limitation results in the binding of PII to UMP.
True
In the absence of ammonia, nitrogen fixation is turned off.
False
The Two-Component Regulatory Systems in Bacteria involve sensor kinase and effector kinase.
False
Learn about the regulation of the maltose operon in bacteria, including the role of activator proteins, promoters, and inducers. Explore how enzymes needed for the production of maltose are activated in the presence of maltose in the culture media.
