How do amino acid dehydratases work? (serine/threonine dehydratase) What are the end products?
AA dehydratases work selectively on serine and threonine removing the amine and the hydroxyl group at the same time.
It is actually a 2 step reaction, first removing water, then removing the amine. Serine to pyruvate, threonine to 2-ketobutyrate.
