Uses
They are found as constituents of an increasing group of biologically active peptides. Stereocontrolled syntheses of chiral and racemic key intermediates to thienamycin from d-allo-threonine and trans-crotonic acid.
Definition
ChEBI: D-allothreonine is the D-enantiomer of allothreonine. It occurs as a component of peptido-lipids in certain bacteria. It has a role as a bacterial metabolite. It is an allothreonine and a D-alpha-amino acid. It is an enantiomer of a L-allothreonine. It is a tautomer of a D-allothreonine zwitterion.
Purification Methods
Recrystallise D-allothreonine from aqueous EtOH or 50% EtOH. [Elliot J Chem Soc 62 1950, Birnbaum et al. J Biol Chem 194 455 1952, IR: Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 1961, Beilstein 4 IV 3170.]
