Definition
Meaning and Definition
An enzyme that catalyzes the hydrolysis of arginine into ornithine and urea.
In biochemistry and medicine, it is a manganese-containing enzyme found primarily in the liver that plays a critical role in the urea cycle, enabling the body to dispose of nitrogenous waste. Research often focuses on its role in cellular metabolism, immune response regulation, and potential links to certain diseases.

Common Mistakes When Using “arginase”
- Mispronunciation: stressing the second syllable (e.g., ar-GIN-ase). Correct stress is on the first syllable.
- Misspelling: 'argenase', 'arginaze', 'arginease'.
- Confusing 'arginase' (the enzyme) with 'arginine' (the amino acid it breaks down).
FAQ
Frequently Asked Questions
Arginase is an enzyme, which is a protein that acts as a biological catalyst to speed up a specific chemical reaction.
It is most active in the liver, where it plays a key role in the urea cycle, the process that removes toxic ammonia from the body.
No, it is an extremely rare inherited metabolic disorder. It is one type of urea cycle disorder.
Certain immune cells (like some macrophages) can express high levels of arginase, which depletes arginine in the tumour microenvironment. This can suppress the activity of cancer-fighting T-cells, making it a potential therapeutic target.
An enzyme that catalyzes the hydrolysis of arginine into ornithine and urea.

Memory Aids
Mnemonic
Imagine an ARGONAUT (sounds like 'Argi-') on a ship in a HAZE (sounds like '-nase'), splitting a large rock named 'Arginine' into two smaller rocks named 'Ornithine' and 'Urea'. The argonaut is the enzyme doing the splitting.
Conceptual Metaphor
A RECYCLING PLANT WORKER or a MACHINE TOOL that precisely cuts a specific molecule (arginine) into two separate, useful parts (ornithine and urea).
