Adenine Methyltransferase

Adenine methyltransferase is an enzyme that adds a small chemical group called a methyl group to adenine bases within DNA. This modification plays a key role in regulating gene activity, protecting bacteria from viruses, and maintaining genetic stability. By marking certain DNA regions, adenine methyltransferase influences how genes are turned on or off, and helps distinguish between the organism's own DNA and foreign DNA, such as invading viruses. This process is essential for various cellular functions and is also a focus in scientific research and biotechnology applications.
