Abstract
A novel L-arabinose isomerase active enzyme and its corresponding gene, derived from a thermophilic source are provided. The enzyme is suitable for the production of D-tagatose, a useful low-calorie sweetener. The enzyme may be obtained from a Thermoanaerobacter species such as Thermoanaerobacter mathranii.
Claims15
An L-arabinose isomerase capable of isomerizing D-galactose to D-tagatose, which isomerase has at least 90% sequence identity to the sequence of SEQ ID NO:2.
