Characterization of Pearl Millet Prolamins
We report the physical-chemical characterization of the major alcohol-soluble proteins present in seeds of pearl millet (Pennisetum glaucum) by SDS-PAGE, bidimensional gel electrophoresis, MALDI-TOF / MS and RP-HPLC. We demonstrate the presence of three major prolamins, called A-, B- and C-pennisetin with mass values around 27, 22 and 12 kDa, respectively. We present partial amino acid sequences of these major proteins, which should allow the posterior isolation of the respective genes.
Keywords: pearl millet prolamin; pennisetin; pennisetum galaucum; prolamin; seed storage protein

Publication date: 01 June 2002
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
