摘要

Methyl transfer reactions play important roles in many biological phenomena, wherein the methylation cofactor S-adenosyl-L-methionine (SAM) serves as the important currency to orchestrate those reactions. We have developed a fluorescent-probe-based high-throughput screening (HTS) system to search for the compounds that control cellular SAM levels. HTS with a drug repositioning library revealed the importance of catechol-O-methyltransferase (COMT) and its substrates in controlling the SAM concentrations and histone methylation levels in colorectal tumor cells.
