When seeds germinate nearly all the proteins are degraded in senescing storage tissue cells. All these proteins act as amino acid reserves which are mobilized to nourish the seedling. Nevertheless, the major amount of the seeds' protein reserve consists of a few enzymatically inactive, abundant, genuine storage proteins. In their metabolism the conflicting processes of biosynthesis, protein turnover and breakdown, are temporally separated. No degradation of correctly formed storage proteins was… CONTINUE READING
