These 4 proteins constituted a high proportion of the total protein in bark increasing from 46 to 70% of the total protein during senescence. The 4 major proteins appeared to serve a storage role and consisted of many heterogeneous polypeptides of different isoelectric points. Twenty one, thirteen, seven, and twenty one heterogeneous polypeptides were found in those 4 major proteins, respectively. Each of the 4 major proteins had similar amino acid composition in their hydrolysates with approximately 40% of the total protein in basic amino acids, asparagine, glutamine, and their amides. The highest proteolytic activity was found when the 20 kD protein were used as a substrate.","During regrowth, a slightly greater degradation of the four dominant proteins was observed. A preferential degradation of some bark proteins differing in electrical charges was also found. Nonetheless, the protein degradation was not limited to a few protein species.","Made available in DSpace on 2014-12-16T20:45:13Z (GMT).
