ndoA | ndoAI | BSU04660 | BSU04650 | Endoribonuclease toxin; Toxic component of a type II toxin-antitoxin (TA) system. Specific for 5'-UACAU-3' sequences, cleaving after the first U. Yields cleavage products with 3' phosphate and 5' hydroxyl groups. Cannot digest substrate with a UUdUACAUAA cleavage site. Overexpression is toxic for cell growth (shown in E.coli), probably by inhibiting protein synthesis through the cleavage of single-stranded RNA. The toxicity is reversed by the antitoxin EndoAI. Toxin activity cannot be inhibited by MazE from E.coli. The EndoA-EndoAI complex does not seem to bind its own promoter. | Antitoxin EndoAI; Antitoxin component of a type II toxin-antitoxin (TA) system.
