Members of this family of sugar isomerases belong to the cupin superfamily and consist of group I and II of D-lyxose isomerases [3]. The enzyme from Cohnella laevoribosii has been shown to be specific for D-lyxose, L-ribose, and D-mannose [1]. E. coli sugar isomerase (EcSI) shows a preference for D-lyxose and D-mannose [2] and its active site is highly similar to YdaE from the sigma B regulon of Bacillus subtilis [3].	Domain
