英文摘要: Abstract(#br)The methylation of DNA, RNA, and proteins plays crucial roles in numerous biological processes, including epigenetic control, virus replication, and cell differentiation. In mammals, the rate-limiting step of the S -adenosylmethionine-dependent methylation process is exclusively controlled by S -adenosylhomocysteine (S-AdoHcy) hydrolase (SAHH). SAHH hydrolyzes S-AdoHcy to adenosine and homocysteine (Hcy) and is therefore a potential therapeutic target for various diseases, including cancer, malaria, and viral diseases. However, a simple and highly sensitive assay for the evaluation of SAHH activity, particularly for drug discovery, had not yet been developed. Here we present the development of a fluorescence-based assay for the measurement of SAHH activity in biological...
