Pathwayi: glutathione biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes glutathione from L-cysteine and L-glutamate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Glutamate--cysteine ligase (gshA)
  2. Glutathione synthetase (gshB)
This subpathway is part of the pathway glutathione biosynthesis, which is itself part of Sulfur metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes glutathione from L-cysteine and L-glutamate, the pathway glutathione biosynthesis and in Sulfur metabolism.
