Research Abstract

天然には微量にしか存在しない「希少糖」は糖としての食品分野への応用だけではなく医療分野においても希少糖の利用価値が期待されている。本研究は「希少糖」の生産に利用される酵素のより効率的な生産を目指した分子設計に有用な情報を得ることを目的に、希少糖生産酵素の構造・機能解析を行った。本研究において、Pseudomonas stutzeri由来L-ラムノースイソメラーゼについては変異酵素を触媒機構に関する詳細な情報が得られ、Pseudomonas cichorii由来D-タガトース3-エピメラーゼとBacillus pallidus由来D-アラビノースイソメラーゼの構造を新たに決定した。
