Differences in hepatic sulfur amino acid metabolism between 2- and 30-month-old mice. MAT, methionine adenosyltransferase; SAHH, S-adenosylhomocysteine hydrolase; BHMT, betaine homocysteine methyltransferase; MS, methionine synthase; MTHFR, methylenetetrahydrofolate reductase; CβS, cystathionine β-synthase; CγL, cystathionine γ-lyase; CDO, cysteine dioxygenase; CDC, cysteine sulfinic acid decarboxylase; GCL, γ-glutamylcysteine ligase; THF, tetrahydrofolate; ND, not determined. Arrows represent situation in 30-month-old mice relative to 2-month-old mice.
