Xylose isomerase, TIM barrel domain <p> This TIM alpha/beta barrel structure is found in xylose isomerase (<db_xref db="SWISSPROT" dbkey="P19148"/>) and in endonuclease IV (<db_xref db="SWISSPROT" dbkey="P12638"/>, <db_xref db="EC" dbkey="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 <taxon tax_id="387">Rhizobium leguminosarum bv. viciae</taxon> [<cite idref="PUB00012949"/>]. </p>
