Unit 1.2(ciii) - Proteins, Reversible binding of phosphate and the control of conformation Flashcards
1
Q
What do kinases do?
A
Catalyse the transfer of a phosphate group to other proteins
2
Q
The addition or removal of phosphate groups to R groups does what?
A
It can be used to regulate activity of proteins as it can cause reversible conformational change in proteins
3
Q
Phosphorylation is carried out by…?
A
Kinases
4
Q
Dephosphorylation is carried out by…?
A
Phosphates
5
Q
What happens to the terminal phosphate group of the ATP?
A
It is transferred to the R group
6
Q
What does De and Phosphorylation regulate
A
The activity of many cellular proteins, such as enzymes and receptors, is regulated in this
way
7
Q
How are inactive proteins made active?
A
post-translation modification
