Negative supercoiling favors strand separation, and DNA replication, transcription, recombination and repair, all of which involve strand separation. Also able to catalyze the interconversion of other topological isomers of dsDNA rings, including catenanes and knotted rings.

ccdA | ndoA | BSU17930 | BSU04660 | Cytochrome c-type biogenesis protein CcdA; Required for cytochrome c synthesis and stage V of sporulation. Might transfer reducing equivalents across the cytoplasmic membrane, promoting efficient disulfide bond isomerization of proteins localized on the outer surface of the membrane or in the spore coat. | 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. | 0.891 |
