Protein Domain : Universal stress protein A family IPR006015

Type  Family
Description  Transcriptional induction of the uspA gene of Escherichia coli occurs when conditions cause growth arrest; cells deficient in UspA survivepoorly in stationary phase [ ]. The product of uspA has been shown to bea cytoplasmic serine and threonine phosphoprotein. Members of the Usp family are predicted to be related to the MADS-box proteins and bind to DNA[ ]. Some members of the family contain 2 copies of the domain. The structure of a UspA homologue from Methanocaldococcus jannaschii (Methanococcus jannaschii) from has been determined to 1.8 angstroms resolution by using its selenomethionyl derivativeand multiwavelength anomalous diffraction. The protein homodimerises in the crystal; each monomer adopts an open-twisted 5-stranded parallel β-sheet with 2 helices on each side of the sheet []. Although the structureco-crystallised with ATP, the function of the protein is unknown. This entry includes five E. coli Usp paralogues: uspA, uspC, uspD, uspF and uspG [ ].
