4.1.2.42 D-threonine aldolaseIUBMB Comments
A pyridoxal-phosphate protein that is activated by divalent metal cations (e.g. Co2+, Ni2+, Mn2+ or Mg2+) [1,2]. The reaction is reversible, which can lead to the interconversion of D-threonine and D-allothreonine . Several other D-beta-hydroxy-alpha-amino acids, such as D-beta-phenylserine, D-beta-hydroxy-alpha-aminovaleric acid and D-beta-3,4-dihydroxyphenylserine, can also act as substrate .

D-threonine acetaldehyde-lyase (glycine-forming)
A pyridoxal-phosphate protein that is activated by divalent metal cations (e.g. Co2+, Ni2+, Mn2+ or Mg2+) [1,2]. The reaction is reversible, which can lead to the interconversion of D-threonine and D-allothreonine [1]. Several other D-beta-hydroxy-alpha-amino acids, such as D-beta-phenylserine, D-beta-hydroxy-alpha-aminovaleric acid and D-beta-3,4-dihydroxyphenylserine, can also act as substrate [1].

in a systematic study, 21 ring-substituted benzaldehydes are reacted with glycine under catalysis with a L-threonine aldolase (LTA) from Pseudomonas putida and a D-threonine aldolase (DTA) from Alcaligenes xylosoxidans to form the corresponding beta-hydroxy-alpha-amino acids

-
the enzyme shows high activity toward aromatic aldehydes with electron-withdrawing substituents. The substrate profiling indicates that the enzyme accepts a wider range of acceptor substrates and is more active toward aromatic aldehydes bearing electron-withdrawing groups than those with electron-donating substituents. Molecular docking studies suggest that the substituent on the benzene ring of the substrate is critical in determining the enzyme activity and stereoselectivity by affecting the interaction between the beta-OH-group of the substrate and the manganese ion
