SAHH Adenosylhomocysteine is a competitive inhibitor of S-adenosyl-L-methionine-dependent methyl transferase reactions; therefore adenosylhomocysteinase may play a key role in the control of methylations via regulation of the intracellular concentration of adenosylhomocysteine. Belongs to the adenosylhomocysteinase family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
