- Methionine Metabolism
- these pathways share 3 common reactions with both including the conversion of methionine to s-adenosylmethionine (sam),the utilization of sam in diverse transmethylation reactions yielding a methylated product plus s-adenosylhomocysteine, and the cleavage of s-adenosylhomocysteine to yield homocysteine and adenosine. the transulfuration reactions that produce cysteine from homocysteine and serine also produce α-ketobutyrate, the latter being converted first to propionyl-coa and then via a 3-step process to succinyl-coa.
