Abstract:	The N-linked sugar chains were liberated as oligosaccha-ridesfrom octopus rhodopsin by hydrazinolysis. Most of the oligosaccharideswere neutral, and separated into two major components by columnchromatography using immobilized lectins and Bio-Gel P-4. Structuralanalysis of the one major component by sequential exoglycosidasedigestion, chemical fragmentation in combination with meth-ylationanalysis revealed that it is a nonasaccharide; Man ${alpha}$ 1 $->$ 6(Gaiβ1 $->$ 3GlcNAcβ1 $->$ 2Man ${alpha}$ 1 $->$ 3)Manβ1 $->$ 4GlcNAcβ1 $->$ 4(Galβ1 $->$ 4Fuc ${alpha}$ 1 $->$ 6)GlcNAcThis structure is quite unique in that a novel galactosylatedfucose residue is attached to the reducing terminal N-acetyl-glucosamineresidue. galactosylated Fuc N-linked sugar chain novel structure octopus rhodopsin
