Radioactive methionine was injected into the thorax of honey bees. After several hours, mitochondrial and supernatant proteins were prepared from thorax and hydrolyzed with pronase. In these digests labelled N-formyl- and N-acetyl-methionine were detected. The latter was about evenly distributed between the two fractions, while the bulk of formyl-methionine was present in mitochondrial protein. Control experiments exclude a bacterial origin of these acyl-methionines.
