    Protein Summary

    Pfam update: I have built this as a small family which may bear similarity to the one indicated:
    ID DUF3829
    AC PF12889
    DE Protein of unknown function (DUF3829)
    AU Coggill P

    BM hmmbuild --amino -o /dev/null HMM SEED
    SM hmmsearch -Z 9421015 -E 1000 --cpu 4 HMM pfamseq
    TP Family This is a small family of proteins from several bacterial species, whose function is not known. It may, however, be related to the GvpL_GvpF family of proteins, Pfam:PF06386.

    Gene BF3319 from Bacteroides fragilis nctc 9343 encodes an all alpha-helical protein, that shows no Pfam hit.
    The protein structure, 3iee, contains a monomer in the crystallographic asymmetric unit, which is also a biological unit.

    Fig.1. 3iee structure.

     Dali hits ligand binding domain of aspartate receptor (2asr, Z=9.7, rmsd=2.4A, 100 Ca aligned, 7% id), apolipoprotein E (1ya9, Z=9.5, rmsd=2.9A, 101 Ca aligned, 7% id) and acethylcholine receptor protein, alpha chain (1oed, Z=9.4, rmsd=2.7A, 101 Ca aligned, 7% id). As shown below, N-terminal of 3iee (green) is similar to 2asr (cyan), and C-terminal of 3iee (green) is similar to 1ya9 (light blue) and 1oed (light pink).

    Fig. 2. 2asr (cyan) superimposes to the N-terminal domian of the 3iee (green) only.

    C-terminal.png

    Fig. 3. 1ya9 (light blue) and 1oed (light pink) superimpose to the C-terminal domain of the 3iee (green).
