Structure of Bacillus subtilis YxkO, a Member of the UPF0031 Family and a Putative Kinase
OverviewOverview
We determined the 1.6-A resolution crystal structure of a conserved, hypothetical 29.9-kDa protein from the SIGY-CYDD intergenic region encoded, by a Bacillus subtilis open reading frame in the YXKO locus. YXKO, homologues are broadly distributed and are by and large described as, proteins with unknown function. The YXKO protein has an alpha/beta fold, and shows high structural homology to the members of a ribokinase-like, superfamily. However, YXKO is the only member of this superfamily known to, form tetramers. Putative binding sites for adenosine triphosphate (ATP), a, substrate, and Mg(2+)-binding sites were revealed in the structure of the, protein, based on high structural similarity to ATP-dependent members of, the superfamily. Two adjacent monomers contribute residues to the active, site. The crystal structure provides valuable information about the YXKO, protein's tertiary and quaternary structure, the biochemical function of, YXKO and its homologues, and the evolution of its ribokinase-like, superfamily.
