gamma-Glutamylcysteine synthetase (GCL)

1 reactions · 1 pathways

Clinical / pharmacological. Rate-limiting for glutathione synthesis; feedback-inhibited by GSH

What it does, reaction by reaction

1 reactions

Glutathione Metabolism (gamma-Glutamyl Cycle) Amino Acid & Nitrogen Metabolism · Cytosol

step 1 Irreversible rate-limiting

L-Glutamate + L-cysteine + ATP -> gamma-glutamylcysteine + ADP + Pi

Converts Glutamate Cysteine ATP into gamma-Glutamylcysteine ADP Pi

Notes

Rate-limiting step; feedback-inhibited by GSH. Cysteine availability is usually the limiting substrate.

Showing all 1 reactions.
