Is cysteine deficiency possible? Is there such a thing as cysteine deficiency in humans or other mammals? What effects would such a deficiency have? As I understand it, most cysteine for humans comes from dietary so...
Cysteine can be produced from methionine through a homocysteine intermediate, and defective genes for the enzymes involved can prevent proper cysteine They might need to take cysteine supplements as well.

Cysteine dioxygenase
Cysteine dioxygenase (CDO) is a non-heme iron enzyme that catalyzes the conversion of L-cysteine to cysteine sulfinic acid (cysteine sulfinate). CDO plays an important role in cysteine catabolism, regulating intracellular levels of cysteine and responding changes in cysteine availability. wikipedia.org
