title: Effect of alpha1,2-mannosidic linkage located in a alpha1,3-branch of Man6GlcNAc2 oligosaccharide on enzyme activity of recombinant human Man9-mannosidase produced in Escherichia coli.
abstract: We produced the human kidney Man9-mannosidase in Escherichia coli and studied the effect of the alpha-1,2-mannosidic linkage located in the alpha branch of Manalpha1-6(Manalpha1-2Manalpha1-3)Manalpha1-6(Manalpha1-3)Manbeta1-4GlcNAcbeta1-4-GlcNAc, an N-linked oligosaccharide, on the enzyme activity. The alpha1,2-mannose residue influenced the rate of hydrolysis of and substrate preference for other alpha-1,2-mannosidic linkages.
