'''Crystal Structure of Threonine Synthase from Escherichia coli'''
== Function ==
 
[https://www.uniprot.org/uniprot/THRC_ECOLI THRC_ECOLI] Catalyzes the gamma-elimination of phosphate from L-phosphohomoserine and the beta-addition of water to produce L-threonine. To a lesser extent, is able to slowly catalyze the deamination of L-threonine into alpha-ketobutyrate and that of L-serine and 3-chloroalanine into pyruvate. Is also able to rapidly convert vinylglycine to threonine, which proves that the pyridoxal p-quinonoid of vinylglycine is an intermediate in the TS reaction.
