Phenotypes of a mutant
the spore coat does not localize to the spore surface but self-assembles into aggregates in the mother cell cytoplasm [Pubmed|22171814]The protein
Catalyzed reaction/ biological activity
uses ATP hydrolysis to drive self-assembly into static filaments [Pubmed|23267091]ATP hydrolysis drives polymerization of a nucleotide-free filament [Pubmed|23267091]ploymerization depends on a critical threshold concentration of SpoIVA that is only achieved once the protein is recruited to the surface of the developing spore [Pubmed|23267091][SW|Domains]
contains a Walker A ATPase domain[SW|Localization]
