The protein

Catalyzed reaction/ biological activity

• interacts with and activates the pro-[protein|3CB24D493B3282278B7DC61CE3C793DFA815F9E2|SigE] protease [protein|221829E084DA78ACE1C2DFCEB6E59EDA534FF55D|SpoIIGA] in the intermembrane space between the forespore and the mother cell [Pubmed|22111992]

Modification

• likely acylated on Thr-27 [Pubmed|22111992]

[SW|Localization]

• localizes initially to the forespore septal membrane (in a [protein|221829E084DA78ACE1C2DFCEB6E59EDA534FF55D|SpoIIGA]-dependent manner), is then exported to the intermembrane space between the forespore and the mother cell [Pubmed|22111992]
