Abstract

Lanthionine and cystathionine have been isolated in crystalline form from the deproteinized haemolymph of Bombyx mori (silkworm) and Antheraea pernyi (Japanese oak moth) by ion-exchange chromatography. Both compounds have been characterized as the L-enanthiomorphs by enzymatic and physical methods. A preliminary survey of the distribution of lanthionine and cystathionine throughout a number of phyla has been carried out and the results of this, together with some preliminary experiments on the in vivo incorporation of isotopically labeled materials, are reported. The presence of free L-lanthionine in insect issues is invariably associated with a complete absence or, at best, barely detectable traces of cysteine, cystine, and methionine.
