The structure of rice storage protein glutelin precursor deduced from cDNA

Abstract

The complete amino acid sequence of rice storage protein glutelin was determined by the sequencing of the corresponding cDNA. The deduced glutelin precursor has a 37 amino acid signal peptide sequence at the NH 2 terminus, which is followed by a 269 amino acid acidic subunit ( M r = 32 489) and a 193 amino acid basic subunit ( M r = 19 587). The glutelin precursor sequence is homologous to those of pea legumin and soybean glycinin.
