S-adenosyl-L-homocysteine hydrolase (EC 3.3.1.1) (AdoHcyase) is an enzyme of the activated methyl cycle, responsible for the reversible hydratation of S-adenosyl-L-homocysteine into adenosine and homocysteine. AdoHcyase is an ubiquitous enzyme which binds and requires NAD+ as a cofactor.
AdoHcyase is a highly conserved protein [1] of about 430 to 470 amino acids. As signature patterns, we selected two highly conserved regions. The first pattern is located in the N-terminal section; the second is derived from a glycine-rich region in the central part of AdoHcyase; a region thought to be involved in NAD-binding.
Last update:April 2006 / Pattern revised.
