    Phenotypes of a mutant

  • the mutation suppresses the mucoid phenotype of ''[gene|86C729C7D5ABEE519ADC4A893940600BBB655EF1|motA]'' or ''[gene|FE56753D061344B0F10A6523F49C5C7356AA40B6|motB]'' mutants due to loss of [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU] phosphorylation and concomitant reduced expression of the ''[gene|86C05126ADBA22BB1771B1FA3D214B2E7A36311E|capB]-[gene|D66994D077D1382B88FF65075E44C2A31089548F|capC]-[gene|A696434A086A428D411CAF45B37CD8F82AC2503F|capA]-[gene|6B61DCE8D27776EBF942621D3AE90F410FD13F37|capE]'' operon [Pubmed|24296669]

    • The protein

    Catalyzed reaction/ biological activity

  • autophosphorylation, autodephosphorylation, phosphorylation of [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU] on Asp-56 [Pubmed|1901568]
  • ATP + protein L-histidine --> ADP + protein N-phospho-L-histidine (according to UniProt)

    • [SW|Domains]

  • aa 12 ... 170: unknown DegS domain
  • [SW|Histidine kinase domain] (aa 183-385) (according to UniProt)
  • aa 289 ... 384: HATPase_c

    • Modification

  • phosphorylation on Ser-76 [Pubmed|17218307], this stimulates phosphotransfer from His-189 to [protein|D343D2096664A972026D911E7A17A35C7B1CD1C9|DegU] [Pubmed|21304896], the phosphorylyation is performed by [protein|E0097A00C82136BB0B1FB89FBA177E28A4EC3D54|PrkD] ''in vitro'' [Pubmed|21304896]
