Maintenance Methyltransferase

Maintenance methyltransferase is an enzyme that preserves DNA methylation patterns during cell division. It recognizes specific methylation marks on the DNA strand and adds methyl groups to corresponding unmethylated bases on the newly synthesized strand. This process ensures that gene regulation patterns are correctly passed from one cell generation to the next, maintaining cellular identity and function. Essentially, maintenance methyltransferase acts as a molecular copykeeper, maintaining consistent epigenetic information across cell generations.
