    Protein Summary

    This target, NP_637619.1, is a general stress protein from Xanthomonas campestris. A PFAM assignment of this protein can not be made on the basis of its sequence yet.

    The core of the protein is a half-closed b-barrel. The b-barrel is nearly closed by a helix which is oriented at an angle (Fig 1). The overall structure resembles that of a FMN-binding split barrel fold protein. However, there is no FMN or any ligand bound at the FMN binding site.

    Fig 1. The monomer structure consists of a core split-barrel domain.

    There are three monomers in crystallographic asu which form a hexamer as a biological unit. The c-terminal region is involved in the oligomerization (Fig 2).

    There are several structural homologs of the protein: 1axj 1ci0 1g76 1nrg 1rfe 1t9m 1ty9 1vl7 1w3o 1w9a 1xhn 2a2j 2arz 2asf 2fg9 2fhq 2fur 2hhz 2hq7 2hq9 2htd 2hti 2i02 2i51 2iab 2ig6 2ol5 2ou5 2q9k 2qea 2re7 3ba3. Fig 3 shows the alignment of a few proteins on this traget.

    The b-barrel core is the aligning template. Most of these proteins have the FMN-binding split barrel fold. It's possible that this target could bind FMN or FAD in order to perform its function. In that case this protein may belong to PFAM PF01243 or PF01613.
