Abstract
Suspension‐cultured cells of rice secrete α‐amylase into the culture medium. It has been shown that the mature form of the α‐amylase contains xylose‐bearing N‐linked oligosaccharide: and We demonstrate that suspension‐cultured cells of rice secrete α‐amylase containing oligomannose‐type oligosaccharides in the presence of 1‐deoxymannojirimycin or tris(hydroxymethyl)aminomethane. On the other hand, α‐amylase purified from germinated rice seedlings contains several kinds of oligomannose‐type and N‐acetyllactosamine‐type oligosaccharides. The processing pathway of oligosaccharide moieties in rice cells is discussed on the basis of a comparison of these oligosaccharides structures.This publication has 43 references indexed in Scilit:
