Question

Which type of enzyme removes a phosphate group from a target protein?

a) Kinase
b) Ligase
c) Phosphatase
d) Synthase

Answer 1

A phosphatase enzyme removes a phosphate group from a protein, thus reversing the action of kinases that add these groups.

Step-by-step explanation:

The type of enzyme that removes a phosphate group from a target protein is known as a phosphatase. A phosphatase is responsible for removing phosphorylated amino acids from proteins by cleaving the phosphate group from phosphorylated amino acid residues, such as serine, threonine, and tyrosine residues. It is important to note that phosphatases act in contrast to kinases, which add phosphate groups to proteins. Therefore, the correct answer to the question is c) Phosphatase.
