Describe the difference bettween a kinase and a phosphataseS
Describe the difference bettween a kinase and a phosphatase.
Solution
Kinase
Phosphatase
catalyze the phosphorylation reactions by the addition of phosphate groups from ATP to protein molecules.
catalyze the dephosphorylation reactions by removing of phosphate groups from substrates.
The phosphorylation reaction is unidirectional
The dephosphorylation reaction is bidirectional
Kinase uses ATP to obtain phosphate groups
Phosphatase use water molecules to remove phosphate groups
Proteins that are activated by a kinase
Proteins deactivated by a phosphatase.
