    Protein Summary

    Gene BSU32610 encodes NP_391141.1, a protein with 328 residues from Bacillus subtilis, a Gram-positive and catalase-positive bacterium commonly found in soil.  The results from NCBI sequence alignments suggests that this protein may be a sugar isomerase, which belongs to the SIS domain family (PF01380). In the conserved isomerase domain, Ser 81, Ser 83, Thr 86, His82, Ser35 may be involved in the H-Bonding network for sugar substrates binding. There are eight  3eua molecules in each asymmetric unit.  The interface interaction suggests that the biomolecule of 3eua may be a dimer.

    Figure 1. The 3eua molecule consists of two domains. The conserved isomerase domain

    locates in the N-terminal domain and near to the interface of two domains.

    Figure 3. 3eua (green) is structurally similar to 1M0R, 2AML, 2PUV

    and 2VF5 with a conserved isomerase catalytic site.

    Figure 4. In the conserved sugar isomerase domain of 3eua, residues Ser 81, Ser 83,

    Thr 86, His82, Ser35 maybe involved in a H-bond network for sugar substrates binding.
