METTL5 Activators

Chemical activators of METTL5 include a variety of compounds that contribute to the protein's methylation activity. S-Adenosylmethionine (SAMe) is a primary methyl donor in numerous methylation reactions, and its availability is a direct contributor to the activation of METTL5. The synthesis of SAMe is dependent on the methionine cycle, where Methionine serves as a precursor. In this cycle, Betaine donates a methyl group to homocysteine to regenerate Methionine, which is then adenosylated to form S-Adenosylmethionine. This cycle is complemented by Folic Acid and Vitamin B12 (Cobalamin), which are necessary for the conversion of homocysteine back to Methionine, thereby ensuring a consistent supply of SAMe for use by METTL5. Vitamin B12 in the form of Cobalamin is specifically necessary for the methionine synthase reaction, which is integral to this process.

Additionally, Choline can be metabolized to Betaine, which, as mentioned, participates in the methionine cycle. Magnesium and Zinc both serve as essential cofactors for enzymes in this cycle. Magnesium is necessary for the function of methionine adenosyltransferase, the enzyme responsible for the synthesis of SAMe, while Zinc may also serve as a structural or catalytic cofactor for this enzyme, thus enhancing the activation of METTL5. Pyridoxal phosphate, the active form of Vitamin B6, acts as a coenzyme for transsulfuration enzymes, which helps to maintain the necessary levels of Methionine for SAMe production. Nicotinamide adenine dinucleotide (NAD+) is a cofactor in the conversion of homocysteine to Methionine, indirectly supporting the methylation capacity of METTL5. Lastly, Serine is involved in the folate cycle, which ensures an adequate supply of one-carbon units for Methionine synthesis, thereby sustaining the activation of METTL5 through the generation of SAMe. All these compounds work in a concerted manner to ensure the active methylation function of METTL5 is maintained by providing the necessary substrates and co-factors required for its enzymatic activity.
