General Information
Term transsulfuration ID (Ontology) GO:0019346 (Gene Ontology)
Definition The interconversion of homocysteine and cysteine via cystathionine. In contrast with enteric bacteria and mammals, Saccharomyces cerevisiae has two transsulfuration pathways employing two separate sets of enzymes.
Also Known As "transsulphuration"
