Pathway of transsulfuration and methionine synthesis in Neurospora crassa . Cystathionine β-lyase, encoded by the met-2+ gene, is shown in its role in the conversion of cystathionine to homocysteine. Cystathionine γ-lyase (encoded by cys-16+), which converts cystathionine to cysteine, has been characterized previously [19]. Abbreviations: SAM, S-adenosylmethionine; SAH, S-adenosylhomocysteine.
