Functioni

May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.UniRule annotation

Catalytic activityi

S-adenosyl-L-homocysteine + H2O = L-homocysteine + adenosine.UniRule annotation

Cofactori

NAD+UniRule annotationNote: Binds 1 NAD+ per subunit.UniRule annotation

Pathwayi: L-homocysteine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-homocysteine from S-adenosyl-L-homocysteine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Adenosylhomocysteinase (ahcY)
This subpathway is part of the pathway L-homocysteine biosynthesis, which is itself part of Amino-acid biosynthesis.
