The following text describes a protein:
Function:
Toxic component of a toxin-immunity protein module, which functions as a cellular contact-dependent growth inhibition (CDI) system. A site-specific general tRNA nuclease, the C-terminus (residues 2201-2334) removes 2 or 4 nucleotides from the 3' end of at least 4 tRNAs (upon expression in E.coli), possibly endonucleolytically. The nuclease activity is neutralized by expression of the cognate immunity protein WapI from the same strain, but not its homolog from 2 other B.subtilis strains. The C-terminus cannot be expressed on its own in E.coli, however it can be cloned in the presence of its cognate immunity protein gene. Cell contact is necessary for growth inhibition. Unlike the LXG toxin-immunity modules, WapAI mediates competition under shaking culture conditions.
Subcellular Localization:
Secreted, cell wall. Secreted. Note=Probably exported by a SecA-dependent pathway.
Domain:
Has two ligand-binding domains; the N-terminus has three 101 AA repeats which are responsible for cell wall binding; the C-terminus consists of two blocks of residues with a conserved motif repeated 31 times.
