This TIM alpha/beta barrel structure is found in xylose isomerase (Swiss:P19148) and in endonuclease IV (Swiss:P12638, EC:3.1.21.2). This domain is also found in the N termini of bacterial myo-inositol catabolism proteins. These are involved in the myo-inositol catabolism pathway, and is required for growth on myo-inositol in Rhizobium leguminosarum bv. viciae [1].	Domain
