Processing of the 2S storage protein pronapin in Brassica napus and in transformed tobacco.

Abstract excerpt

The 2S protein napin in Brassica napus is synthesized as a proprotein from which an N-terminal an an internal propeptide are removed. In order to investigate the mechanism of 2S storage-protein processing, N-terminal sequences were determined for the light and heavy chains of all major napin isoforms isolated. Mutants of a napin gene, with deletions of different portions of the propeptides, were transformed into...
