Abstract:
The synthesis and processing of cereal lectins was followed in vivo. The initial translation products of lectin genes are higher molecular weight (28 K) precursors, which are post-translationally processed in a single step into authentic lectin polypeptides (23 K). The conversion of precursor into mature product is a rather slow process (the precursor has a half life of 36 min) and is apparently not a prerequisite for biological activity since the precursor exhibits sugar binding activity. Because of the striking resemblances between the processing of cereal lectins and vectorial processing of cytoplasmatically made chloroplast, mitochondrial and glyoxysomal proteins, vectorial processing of cereal lectins might be a means of transporting these proteins through a membrane into an extra-cytoplasmic compartment.
