Phenotypes of a mutant

• mis-assembly of the outer spore coat [Pubmed|22171814]
• inactivation of ''[gene|825AD8D4315A85CD384F9AF6AD894E38E57C88F7|cotE]'' reduces sporulation efficiency to 49.1% that of wild type cells [Pubmed|26735940]

The protein

Catalyzed reaction/ biological activity

• assembly of the [protein|9C59B51FC19FC83BD14272008BD441833DD1738E|CotC]-[protein|EB690FA075EAC3E298C47AED082B5FC21E8F8F46|CotU] complex [Pubmed|20023017,18065538]

[SW|Localization]

• encircles the forespore with a biased accumulation on the mother cell-proximal face of the forespore [Pubmed|23267091,22463703]
• outer spore coat, localization depends on [protein|A25C1530DA7BB007A288E525404E9F775E219FE8|SpoIVA] [Pubmed|22773792,22171814]
