Protein Family Models

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].

This enzyme is also called serine deaminase and L-serine dehydratase 1. L-serine ammonia-lyase converts serine into pyruvate in the gluconeogenesis pathway from serine. This enzyme is comprised of a single chain in Escherichia coli, Mycobacterium tuberculosis, and several other species, but has separate alpha and beta chains in Bacillus subtilis and related species. The beta and alpha chains are homologous to the N-terminal and C-terminal regions, respectively, but are rather deeply branched in a UPGMA tree. This enzyme requires iron and dithiothreitol for activation in vitro, and is a predicted 4Fe-4S protein. Escherichia coli Pseudomonas aeruginosa have two copies of this protein.
