Here, we present a class of selective and sensitive fluorescent biosensors for S-adenosyl-l-homocysteine (SAH) that provide a direct “mix and go” activity assay for S-(5′-Adenosyl)-L-homocysteine Hydrolase Activity Assay. Varying amounts of S-(5′-adenosyl)-L-homocysteine were incubated with different amounts of S-(5′-adenosyl)-L-homocysteine hydrolase in the presence of saturating concentration of L-methionine γ-lyase in citrate-phosphate buffer (25 mM, pH 6.4) for 20 min at 37 °C. For inhibition S-Adenosyl-l-homocysteine (SAH) is the biosynthetic precursor to homocysteine. SAH is formed by the demethylation of S-adenosyl-l-methionine. Adenosylhomocysteinase converts SAH into homocysteine and adenosine.

Due to the donation of methyl group, SAM becomes S-adenosyl-L-homocysteine (SAH). The molecular structure of SAM and SAH was presented in Fig. 2 B. DNA methylation is a reversible process. Under the catalytic effect of DNA demethylase, the methyl group can be replaced by H atom again ( Fig. 2 A), which is considered as passive DNA methylation pattern.

Adenosin kan också genereras från hydrolysen av S-adenosyl-homocystein (SAH). Som svar på hög metabolisk aktivitet extruderas ATP och adenosin till utsidan  Förhöjd nivå av homocystein ses vid brist på folat och/eller kobalaminer.
