However, researchers also noted that the overall clinical effect appeared limited and difficult to reproduce consistently across larger populations

The catalytic active site of tyrosinase contains multiple histidine residues that coordinate with copper ions, forming an active center capable of catalyzing the oxidation of tyrosine

Since oxidized glutathione is formed by the dehydrogenation of two GSH groups through thiol groups, it is often abbreviated as G-S-S-G or GSSG

In summary, as conserved cysteine residues are potential candidates for the redox control of proteins due to their ability to undergo reversible oxidation-reduction reactions, participate in enzyme catalysis, maintain structural integrity, and sense the cellular redox environment, Cys190 conservation across different species underscores its essential role in GSAAT enzyme catalysis or its regulatory function ( Supplementary Figure 1 )
