摘要：

Immobilised glucose isomerase (EC 5.3.1.5) accepted various (2R,3R)-configured aldofuranoses such as D-erythrose, as well as homologous C-5-modified D-ribose derivatives, as substrates. In the case of D-erythrose, quantitative conversion into D-glycero-tetrulose took place. D-Ribofuranoses were converted into the corresponding open-chain 2-ketoses in isolated yields of 65%. Surprisingly, L-erythrose also turned out to be a substrate of this enzyme. (C) 1998 Elsevier Science Ltd.
