Serine degradation
|
Serine can be degraded to pyruvate via three different pathways:
 via direct dehydratation of serine to pyruvate, catalyzed by
serine dehydratase
via serinolysis with glycerate 2-P and phosphoenolpyruvate as
intermediates (catalyzing enzymes: serine pyruvate transaminase,
glycerate dehydrogenase and glycerate kinase).
via cystathionine and cysteine as intermediates (catalyzing enzymes: cystathionine β-synthetase, gamma cystathionase, cysteine desulfhydrase).
