    Protein Summary

    The protein YP_001304724.1 is annotated as Sugar phosphate isomerase/epimerase. YP_001304724.1 belongs to PFAM PF01261 AP_endonuc_2. This consists of TIM alpha/beta barrel structures found in xylose isomerase (P19148) and in endonuclease IV (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].

    There are over 200 structures in PFAM PF01261 family.

    The monomer structure is displayed below.

    The structure is very similar to another JCSG structure 3l23, again a Sugar Phosphate Isomerase/epimerase from Parabacteroides Distasonis ATCC 8503. These two proteins have 51.5% sequence identity and superpose with 1.25A rmsd over 260 out of 282 residues. The superposition of these two structures is shown below.
