A novel threonine aldolase model
Abstract
The AlIII-pyridoxal-catalysed threonine aldolase model reactions of threonine and of a new substrate, β-hydroxyvaline, are followed by quantitative n.m.r. measurements in D2O solution; formation of acetone in the β-hydroxyvaline reaction system provides the first quantitative evidence for C–C bond fission of an α-amino-acid having an α-proton in the presence of pyridoxal and metal ions.
