Answer:
The enzyme responsible for converting ornithine into citrulline is ornithine carbamyl transferase. Here is a detailed explanation of the process:
Ornithine:
- Ornithine is a non-proteinogenic amino acid involved in the urea cycle.
- It is produced from arginine during the breakdown of proteins and is an intermediate in the conversion of ammonia to urea.
Urea Cycle:
- The urea cycle is a series of biochemical reactions that take place in the liver, converting toxic ammonia into urea for excretion.
- Ornithine is a key component of the urea cycle.
Ornithine Carbamyl Transferase:
- Ornithine carbamyl transferase is an enzyme that catalyzes the transfer of a carbamyl group from carbamyl phosphate to ornithine, forming citrulline.
- This enzyme is present in the mitochondria of liver cells.
Citrulline:
- Citrulline is an amino acid that is produced as a result of the conversion of ornithine by ornithine carbamyl transferase.
- It is an intermediate in the urea cycle and is further converted to arginine.
In summary, ornithine is converted into citrulline by the enzyme ornithine carbamyl transferase in the urea cycle. This conversion is essential for the elimination of ammonia from the body and the production of urea.
