NEW PHOSPHORYLASE PRODUCING MICROORGANISM

摘要

Glycosylation or transglycosylation of a specified guanine derivative, namely 9-substituted or non-substituted guanine of formula [I] with a 3-deoxyribose donor such as 3 min -deoxyadenosine in the presence of a nucleoside phosphorylase source such as of microorganism origin is disclosed.
