L-serine dehydratase (EC:4.2.1.13) is a found as a heterodimer of alpha and beta chain or as a fusion of the two chains in a single protein. This enzyme catalyses the deamination of serine to form pyruvate. This enzyme is part of the gluconeogenesis pathway. Members included in this entry adopt and all-helical structure [1].
