Protein Domain : Stage IV sporulation protein A, middle domain IPR046841

Type	Domain
Description	The stage IV sporulation protein A ( ) is an ATPase that has a role at an early stage in the morphogenesis of the spore coat and is required for proper coat localisation to the forespore [ , , ]. A comparative genome analysis of all sequenced genomes of Firmicutes shows that the proteins are strictly conserved among the sub-set of endospore-forming species. This protein contains an ATPase domain at the N-terminal, a structural middle domain and a C-terminal domain that is key for targeting SpoIVA to the outer forespore membrane [].This is the structural middle domain of Stage IV sporulation protein A (SpoIVA) which follows the ATPase domain and the predicted secondary structure suggests that it is composed of two symmetrical units containing α-helices and β-strands [ ].
