    Protein Summary

    YP_400729 (locus: Synpcc7942_1712) from Synechococcus sp. PCC 7942 (elongatus) encodes a hypothetical protein from a PFAM family PF08848 (DUF1818) with a ssDNA-binding transcriptional regulator domain fold, consisting of a repeat of two beta(4)-alpha motifs.

    YP_400729 has strong sequence and structure similarity to another JCSG solved protein, 2it9.

    STRING server reports that function of YP_400729 may be linked with its genomic neighbors: of Synpcc7942_1711, rpoZ (DNA-directed RNA polymerase omega subunit), Synpcc7942_1713 (probable hydrocarbon oxygenase MocD), and Synpcc7942_1714 (Homoserine O-acetyltransferase).

    YP_400729 has significant structural similarity to other proteins from the ssDNA fold, including MRP2 (mitochondrial RNA-binding protein 2; PDB structure 2gia) and to 2ffg, uncharacterized protein from DUF1797 family, which contains only one beta(4)-alpha motif.

    Analysis of the crystallographic packing of YP_400729 using the PQS server indicates that a dimer is the biologically relevant form.
