Crystal structure of Bacillus subtilis toxin MazF in complex with cognate antitoxin MazE

Function

[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] [ENDAI_BACSU] Antitoxin component of a toxin-antitoxin (TA) module. Antitoxin that directly inhibits activity of EndoA in vitro. Upon expression in E.coli counteracts inhibitory effect of mRNA interferase EndoA.[3] [4]

About this Structure

4me7 is a 6 chain structure with sequence from Bacillus subtilis subsp. subtilis str. 168. Full crystallographic information is available from OCA.
