Highlights From Three Articles/References

The following are pieces of information found from three different articles that showcase more information that could be added to improve the article:

1) SymE/SymR may be involved in recycling damaged RNA as part of the stress response for bacteria. Additionally, symE specifically has LexA binding sites that are induced by the stress response.^[1]

2) SymE is a toxin superfamily. Traditionally, antitoxin is sRNA and toxin/antitoxin genes exist in opposite strands of type I systems.^[2]

3) SymE is not hydrophobic and is apparently in the cytoplasm. Its homology is similar to type II toxins, and it is considered an RNase.^[3]
