General annotation (Comments)

Function

Synthesizes glutathione from L-glutamate and L-cysteine via gamma-L-glutamyl-L-cysteine By similarity. HAMAP-Rule MF_00782

Catalytic activity

ATP + L-glutamate + L-cysteine = ADP + phosphate + gamma-L-glutamyl-L-cysteine. HAMAP-Rule MF_00782

ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione. HAMAP-Rule MF_00782

Cofactor

Binds 2 magnesium or manganese ions per subunit By similarity.

Pathway

Sulfur metabolism; glutathione biosynthesis; glutathione from L-cysteine and L-glutamate: step 1/2. HAMAP-Rule MF_00782

Sulfur metabolism; glutathione biosynthesis; glutathione from L-cysteine and L-glutamate: step 2/2.

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00782

Sequence similarities

In the N-terminal section; belongs to the glutamate--cysteine ligase type 1 family. Type 2 subfamily.

Contains 1 ATP-grasp domain.

Sequence caution

The sequence AAT05525.1 differs from that shown. Reason: Erroneous initiation.
