MUTANTS OF BACILLUS SUBTILIS THAT REQUIRE THREONINE OR THREONINE PLUS METHIONINE [PDF]
Journal of Bacteriology, 1950 Mutant strains of microorganisms that require threonine and ones that require methionine have been reported in Neurospora (Horowitz, Bonner, Mitchell, Tatum, and Beadle, 1945), in Escherichia coli (Roepke, Libby, and Small, 1944), and in Bacillus subtilis (Burkholder and Giles, 1947).

ENZYMATIC BREAKDOWN OF THREONINE BY THREONINE ALDOLASE [PDF]
Journal of General Physiology, 1954 1. The enzyme which splits threonine to acetaldehyde and glycine has been partially purified from rat liver (five- to sixfold purification) and the name threonine aldolase proposed for it. 2. The general properties of threonine aldolase have been studied. The enzyme is unstable to a pH below 5. The pH optimum of the enzyme reaction is at
