YDCE protein from Bacillus subtilisYDCE protein from Bacillus subtilis
Structural highlights
1ne8 is a 1 chain structure with sequence from Bacillus subtilis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[ENDOA_BACSU] Toxic component of a toxin-antitoxin (TA) module. Has specificity for UACAU sequences, claving after the first U and yielding cleavage products with 3' phosphate and 5' hydroxyl groups. Overexpression is toxic for cell growth, 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.[1][2]
