-glutamyl kinase (GK) encoded by PRO1 in eukaryotes or proB in prokaryotes, the first enzyme in proline biosynthetic pathway, catalyzes the formation of intermediate -glutamyl phosphate, which if accumulated could partially react with cysteine to generate -GC, and then Gsh2 adds glycine to -GC to form GSH

[Abstract] RTqPCR analyses demonstrated that the transcriptional upregulation of sHSP genes (17.4, 17.6A, 21, 23.5) in ClpD-GFP line #5 was suppressed by the ROS scavenging reagent GSH (500 M, 2 days)
Fluctuations in HPA axis activity, central insulin sensitivity, autonomic tone, gut microbial composition, intestinal permeability, and behavior (e.g., hedonic eating, sleep, spontaneous physical activity) co-evolve with cycle phase and may help explain why ostensibly similar hormonal profiles can yield divergent metabolic phenotypes across individuals or across cycles in the same woman [84,95,171,173]
