Cystine reductase gene
WebFeb 23, 2024 · The intracellular reduction of cystine to cysteine requires NADPH. This causes SLC7A11-high cancer cells to be more dependent on the glucose pentose phosphate pathway (a major provider of NADPH in cells), which in turn is metabolically dependent on glucose ( Figure 2 ). WebMar 6, 2024 · Cysteine can be synthesized from several sources. One source is the metabolism of the other sulfur-containing amino acid, methionine. This begins with formation of S-Adenosyl-Methionine (SAM), catalyzed by methionine adenosyltransferase.
