InterPro : IPR006016

Name  UspA Short Name  UspA
Type  Domain Description  This entry represents a domain found in the universal stress protein UspA [], which is a small cytoplasmic bacterial protein whose expressionis enhanced when the cell is exposed tostress agents. UspA enhances the rate of cell survival duringprolonged exposure to such conditions, and may provide a general"stress endurance" activity.The crystal structure of Haemophilus influenzaeUspA []revealsan alpha/beta fold similar to that of the Methanocaldococcus jannaschii(Methanococcus jannaschii)MJ0577 protein, which binds ATP [], though UspA lacks ATP-bindingactivity.Proteins containing this domain include the TeaD protein from Halomonas elongata. TeaD regulates the ectoine uptake by the transporter TeaABC. TeaD shows an ATP-dependent oligomerisation [].
