Adenosylhomocysteinase (P39954)

Identification
NameAdenosylhomocysteinase
Synonyms
  • AdoHcyase
  • S-adenosyl-L-homocysteine hydrolase
Gene NameSAH1
Enzyme Class
Biological Properties
General FunctionInvolved in adenosylhomocysteinase activity
Specific FunctionAdenosylhomocysteine 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
