Effector immunity protein Tgi2PP
This domain is Tgi2PP found in Pseudomonas protegens. Tgi2PP is part of the Tge2PP- Tgi2PP Effector-immunity pair secreted by the type VI secretion system (T6SS). Tgi2PP interacts predominantly by hydrogen bonding and hydrophobic interactions with Tge2PP via the insertion of the beta-sheet core of Tgi2PP into the substrate-binding groove of Tge2PP. Tgi2PP contains a similar topology to the periplasmic E. coli colicin M immunity protein.
