This family includes the 5-keto 4-deoxyuronate isomerase enzyme EC:5.3.1.17 that is involved in pectin degradation. This family aldo includes bacterial Myo-inositol catabolism (IolB) proteins. The Bacillus subtilis inositol operon (iolABCDEFGHIJ) is involved in myo-inositol catabolism. Glucose repression of the iol operon induced by inositol is exerted through catabolite repression mediated by CcpA and the iol induction system mediated by IolR [2]. The exact function of IolB is unknown. Members of this family possess a Cupin like structure.	Domain
