The removal of a phosphate group from a protein to cause the protein to change its confirmation is called phosphorylation?
No, phosphorylation is the addition of a phosphate group.
What does phosphorylation do to a moleclue?
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.
How is phosphorylation important in a transduction cascade?
Phosphorylation will turn an inactive protein into an active one, which triggers another response in the cell.
What occurs in the in the inner membrane of the mitochondria?
The passing on of excited electrons from protein to protein. This is known as the electron transport chain that occurs in the inner membrane of the mitochondrion.
What is an autophosphorylation?
An autophosphorylation is the phosphorylation of a kinase protein catalyzed by its own enzymatic activity.
What is autophosphorylation?
An autophosphorylation is the phosphorylation of a kinase protein catalyzed by its own enzymatic activity.
Protein phosphorylating enzymes help regulated gene expression by?
protein activation
What is the RB protein?
Retinoblastoma protein regulates the progression past the restriction point between G1 and S phases. It is regulated by phosphorylation.
What does phosphorylation do for a molecule?
it adds a phosphate group Phosphorylation is the addition of a phosphate (PO43−) group to a protein or other organic molecule.
What does a signal transmitted via phosphorylation of a series of proteins do?
They bring a conformational change to each protein.
What Is a kinase?
a protein kinase is a protein that activates another protein. typically through phosphorylation. they often consists of two domains, one that phosphorylates, and one that regulates the phosphotransferase activity.
The regulation of heterotrimeric G-proteins is similar to the regulation of which one of the following processes?
The regulation of heterotrimeric G-proteins is similar to the regulation of signal transduction. Just like in signal transduction, the activation and deactivation of heterotrimeric G-proteins involve different regulatory mechanisms such as phosphorylation, nucleotide binding, and protein-protein interactions. Both processes play crucial roles in cellular signaling and control various physiological functions.
