FAQ
Frequently Asked Questions
No, while most common for proteins, it can refer to the addition of a phosphate group to any suitable organic molecule, such as sugars (e.g., glucose phosphorylation in glycolysis) or lipids.
The process is called 'phosphorylation'. The agent that performs it is often a 'kinase'.
Yes, it is very common. For example, 'The protein is phosphorylated by the kinase' is a standard construction in scientific writing.
Typically, the high-energy molecule adenosine triphosphate (ATP) is the phosphate group donor in biological systems.
To introduce a phosphate group (PO₄³⁻) into a molecule, typically a protein or other organic compound.
Phosphorylate is usually technical/scientific in register.

Memory Aids
Mnemonic
Think of a PHOSPHOrus group being installed LATE in the protein's modification process, like a late-stage upgrade that turns the protein 'on'.
Conceptual Metaphor
A molecular 'on/off switch' or a 'tag' that changes a protein's identity and function.
