    Protein Summary

    The gene 2636534 from Bacillus subtilis encodes a putative asparaginyl hydroxylase  EC: (other names: peptide-aspartate beta-dioxygenase, aspartate beta-hydroxylase), a clavaminate synthases superfamily. The protein contains Cupin 4 superfamily domain PF08007, which includes a large number of hypothetical proteins.  The core of the protein reveals a double-stranded beta-helix (jelly-roll topology) fold type SCOP51181, common for this class of enzymes.  The jelly-roll domain houses conserved amino acid residues involved in Fe2+ binding.  The primary function of asparaginyl hydroxylases is to control the activity of transcription factors in response to changes in the environmental O2 concentration.  In multicellular organisms, under normoxic conditions  the proline and asparagine residues are hydroxylated by prolyl and asparaginyl hydroxylases. These hydroxylations regulate the stability and transcriptional activity of the HIF-1a (hypoxia induced factor) subunit.  It has been shown that hypoxic condition of host cells decreases virulence of certain pathogenic bacterial strains [Ref].  Therefore, it is plausible that pathogenic bacteria utilize asparaginyl hydroxylase to mimic the biochemical state of normoxic condition by keeping host HIF-1 hydroxylated.  In the context of Bacillus subtilis, which is not pathogenic and classified as an obligate aerobe, asparaginyl hydroxylase is probably involved in metabolic regulation.
