Abstract
Glycine and formaldehyde are converted into serine in the presence of a dialyzed, lyophilized enzyme preparation from corn seedlings, with tetrahydropteroylglutamic acid and pyridoxal phosphate as coenzymes. The equilibrium constant of the reaction was calculated for the system at 37.5[degree]C as K = 3.1 X 103. The pH activity curve showed a maximum between 6.6 and 7.0. The effects of the concentrations of the coenzymes were studied. The gly-cine-serine interconverting enzyme is present throughout the seedling and occurs exclusively in the soluble fraction of the cells.Keywords
