===STRUCTURE OF PYROCOCCUS HORIKOSHII SAM HYDROXIDE ADENOSYLTRANSFERASE IN COMPLEX WITH SAH===
== Function ==
 
[https://www.uniprot.org/uniprot/RSAMH_PYRHO RSAMH_PYRHO] Catalyzes the hydrolysis of S-adenosyl-L-methionine (SAM) into adenosine and L-methionine (PubMed:18551689). Is likely stereoselective, specifically hydrolyzing (R)-S-adenosyl-L-methionine ((R)-SAM), the inactive form of the ubiquitous cofactor SAM, and not the active form of SAM, (S)-S-adenosyl-L-methionine (By similarity). Probaly plays a role in preventing accumulation of (R)-S-adenosyl-L-methionine in cells; maintenance of (S)-S-denosyl-L-methionine homochirality is important for cellular health given that the (R)-form is largely inactive as a methyl donor and can function as an inhibitor of methyltransferases (By similarity). Is unable to mediate a fluorination or chlorination reaction with SAM (PubMed:18551689).[UniProtKB:A4X4S2]<ref>PMID:18551689</ref>
