Abstract In 1946, 14C-cyanide made its appearance as an offshoot of the Atomic Energy Program. Our colleague Robert Loftfield built it into 14C-alanine by the Strecker synthesis, and a lusty program directed toward uncovering the unknown mechanism of protein synthesis grew out of this beginning. The necessity for an undiscovered series of steps and enzymes was soon evident. A cell free system ...
