Metabolite Identification

Common Name

S-inosyl-L-homocysteine

Description

S-inosyl-L-homocysteine is a metabolite belonging to the class of nucleoside derivatives. Chemically, it is generated through the deamination of S-adenosyl-L-homocysteine, playing a crucial role in the recycling pathways of S-adenosyl-L-methionine (SAM). In extremophiles such as Methanocaldococcus jannaschii and Thermotoga maritima, S-inosyl-L-homocysteine is produced as part of an alternative metabolic route for SAM regeneration (PMID:38548921 ). The enzyme S-inosyl-L-homocysteine hydrolase, specific for this metabolite, has been identified and characterized, demonstrating its involvement in the hydrolysis and synthesis processes distinct from S-adenosyl-L-homocysteine (PMID:25917907 ). This enzyme exhibits varying Km values for its substrates, including inosine and L-homocysteine (PMID:25917907 ). The presence of S-inosyl-L-homocysteine in the metabolic pathways of certain archaea indicates its significance in the biochemical processes that facilitate methylation reactions and the regeneration of SAM, highlighting its role as an uncommon yet important metabolite in these organisms (PMID:29449933 ).
