label: Reduced glutathione synthetase level
label_lc: reduced glutathione synthetase level
description: Reduced level of the enzyme glutathione synthetase, which catalyzes the last step in the synthesis of glutathione and a deficiency results in low levels of glutathione. Acidosis is due to reduced feedback inhibition of gamma-glutamyl cysteine synthetase in the gamma-glutamyl cycle, which ultimately leads to overproduction and accumulation of 5-oxoproline.
