The oxidation of terminal D-galactofuranose residues of a galactan and a glycoprotein by a D-galactose oxidase preparation from Dactylium dendroides.

A galactan, isolated from the unicellular organism Prototheca zopfii, and a glycoprotein from a hyphal cell-wall fraction of the fungus Pithomyces chartarum have been oxidised by a D-galactose oxidase preparation from Dactylium dendroides. The oxidised polymers were subsequently reduced with sodium borotritide. The site of oxidation was identified as C-6 of non-reducing D-galactofuranosyl residues in both polymers.
