Abstract
By glycerol gradient centrifugation of a detergent‐solubilized plasma membrane fraction from pea tissue, we find a polypeptide of 55 kDa that copurifies with β‐1,3‐glucan synthase activity. An antiserum against this polypeptide adsorbs glucan synthase activity and the 55 kDa polypeptide from digitonin‐solubilized plasma membrane. These results indicate that the 55 kDA polypeptide is involved in pea β‐1,3‐glucan synthase activity.Keywords
