in the majority of cells and tissues, the expression of gclm protein is lower than gclc and gclm is therefore limiting in the formation of the holoenzyme complex. thus, the sum total of cellular gcl activity is equal to the activity of the holoenzyme + the activity of the remaining monomeric gclc. composed of a catalytic and a modulatory subunit. the catalytic subunit is necessary and sufficient for all gcl enzymatic activity, whereas the modulatory subunit increases the catalytic efficiency of the enzyme. mice lacking the catalytic subunit (i.e., lacking all "de novo" gsh synthesis) die before birth. mice lacking the modulatory subunit demonstrate no obvious phenotype, but exhibit marked decrease in gsh and increased sensitivity to toxic insults.
