Abstract/OtherAbstract:
Cathepsins B and H from rat liver contain one asparagine-linked sugar chain in each molecule. The sugar chains were liberated from the polypeptide portions by hydrazinolysis followed by N-acetylation and NaB3H4 reduction. Paper electrophoresis of the radioactive oligosaccharide fractions revealed that they were mixtures of neutral oligosaccharides only. After fractionation by gel filtration the structure of each oligosaccharide was studied by sequential exoglycosidase digestion in combination with methylation analysis. The sugar chain of cathepsin H was a high mannose type oligosaccharide which varied in size from 5 to 9 mannose residues; on the other hand the major oligosaccharide of cathepsin B was a tetrasaccharide whose structure was Manalpha 1----6Manbeta 1----4GlcNAcbeta 1----4GlcNAc.
