A kinase‐inverting β‐glycoside hydrolase hybrid reaction going one way: The levoglucosan kinase from L. starkeyi converts 1 with inversion of anomeric configuration to yield α‐2. Backwards reaction of 2, or of “activated” analogues 3 and 4, is not detectable, probably reflecting a large energy barrier comprising conformational restrictions of the sugar ring.

Starkeyi菌中左旋葡聚糖激酶的生化特性和机理分析

激酶逆转β-糖苷水解酶杂交反应的一种方式是：来自starkeyi的左旋葡聚糖激酶将1转化为异头构型，从而产生α- 2。无法检测到2或“激活的”类似物3和4的向后反应，这可能反映了包括糖环构象限制在内的大能量垒。
