Rhamnogalacturonan I (RG-I) was isolated from the pectin of the cell wall of xylem differentiating zones of sugi (Cryptomeria japonica D. Don, gymnosperm) by digesting with endo-alpha-1,4-polygalacturonase followed by gel-permeation chromatography. Structure of RG-I was characterized by glycosyl composition and glycosyl linkage analyses, partial acid hydrolysis, and lithium (Li)-treatment in ethylenediamine. The oligosaccharides produced by partial acid hydrolysis showed the backbone of RG-I to… CONTINUE READING
