Other notes

Occasionally, small volumes of a vial (s) of active protein GGT1 may become trapped in the product vial seal during shipping and storage. If necessary, briefly centrifuge the vial in a benchtop centrifuge to dislodge any liquid on the lid of the container. Some products may need to be shipped with dry ice and an additional fee may apply for dry ice.

NCBI Summary for GGT1

The enzyme encoded by this gene is a type I gamma-glutamyltransferase that catalyzes the transfer of the glutamyl moiety of glutathione to a variety of amino acids and dipeptide acceptors. The enzyme is made up of a heavy chain and a light chain, which are derived from a single precursor protein.

It is expressed in tissues involved in absorption and secretion and can contribute to the etiology of diabetes and other metabolic disorders. Multiple alternatively spliced ​​variants have been identified. There are several related genes present on chromosomes 20 and 22, and putative pseudogenes for this gene on chromosomes 2, 13, and 22.

UniProt feedback for GGT1

GGT1: initiates the breakdown of extracellular glutathione (GSH), provides cells with a local cysteine ​​supply and contributes to maintaining the level of intracellular GSH. It is part of the cellular antioxidant defense mechanism. It catalyzes the transfer of the glutamyl moiety of glutathione to amino acids.
