    Protein Summary

    Gene Exig_2160 from Exiguobacterium sp. 255-15 encodes the YP_001814629 protein that contains two domains belonging: the conserved N-terminal PH domain  to PF08000, and the oligomerization C-terminal anti-parallel helix to PF11724

    SCOP classifies the PH domain of 3b77 inside the all-beta class, PH domain superfamily, BPHL domain family. According to DALI, 3b77 PH-domain is structurally similar to those PH domains in 3hsa, 3dcx , 1lw3, and 1kz7 (Z=10-8).



    This protein contains a conserved PH domain (40-130). Conserved domain colored red below:

    12 monomers form a pretty dodecamer that is similar to a dome-shaped cap. Conserved residues are mostly located on the PH domain. Although the function of the protein is unknown, it is possible that the sites of interest are located at the bottom of ring formed by  the PH domains. 

    Sequence conservation (14 full length homologs):


    Electrostatic surface seems to correlate well with conserved surface on PH domain ring

    Does this protein bind to other protein for its function (i.e. may not an enzyme itself)? More work is needed to figure out functional clue. Based on gene neighborhood analysis, it is possible that this protein is involved in prespore regulatory pathways in Bacillus subtilis.
