L-cystathionine + H2O = L-homocysteine + NH3 + pyruvate.

Cofactori

Pathwayi: L-methionine biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes L-homocysteine from L-cystathionine.
Proteins known to be involved in this subpathway in this organism are:
  1. Putative cystathionine beta-lyase (IRC7), Cystathionine beta-lyase (STR3)
This subpathway is part of the pathway L-methionine biosynthesis via de novo pathway, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-homocysteine from L-cystathionine, the pathway L-methionine biosynthesis via de novo pathway and in Amino-acid biosynthesis.
