DNA (cytosine-5) methyltransferases (m5C MTase) introduce a methyl group onto carbon 5 of the target cytosine through a covalent intermediate between the protein and the target cytosine (9). During this process, the cytosine is flipped 180° out of the DNA backbone into an active site pocket of the enzyme (10). WebCytarabine, also known as cytosine arabinoside ( ara-C ), is a chemotherapy medication used to treat acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), chronic myelogenous leukemia (CML), and non-Hodgkin's lymphoma.
