Resumen:
Helianthinins are storage proteins present in Helianthus annuus seeds belonging to the 11S globulin family. We describe here that a fraction of the helianthinins is phosphorylated. This conclusion is supported by different criteria including identification by MALDI-TOF of major protein bands revealed with a specific dye for phosphoproteins, anti-phosphoserine antibody and binding to a phosphoprotein affinity matrix. Moreover, we show that the phosphorylation status of helianthinins changes following germination.
