The results showed that people with long-term insomnia averaged 30% lower GABA levels in the brain than the normal sleeping control group.[ref] Medications that block the GABA-B receptors (thus altering the recycling of GABA) alter sleep patterns and decrease slow-wave sleep

In rats, GCLC has a Km for glutamate that is about 10-fold higher than that of the GCL holoenzyme, which is higher than the cellular glutamate concentration in most tissues GCL is specific for the glutamyl moiety and is regulated physiologically by: (a) non-allosteric feedback competitive inhibition by glutathione (GSH) (Ki = 2.3 mM) which involves binding of GSH to the glutamate and another site on the enzyme [8, 9] and (b) availability of its precursor, cysteine [1]
