抄録

Shewanella amazonensis α-mannosidase (Sama99), a member of glycoside hydrolase family 99, was expressed in Escherichia coli. The purified Sama99 hydrolyzed pyridylamino (PA)-sugars, Glc1Man9GlcNAc2-PA, and Glc3Man9GlcNAc2-PA, and the product was probably a pyridylamino-decasaccharide in both cases. The mode of action of Sama99 was found to be essentially identical to that of rat endo-α-1,2-mannosidase, but the specificity of Sama99 was low.
