RelE with RBS and double terminator
A toxin-antitoxin system is a system composed of two gene products, of which one specifies a cell toxin and the other an antitoxin, which neutralizes the toxic effect caused by the toxin. In E. coli K-12 the cytotoxin RelE and antitoxin RelB comprise such a system [1]. The part BBa_K2449028 encodes the antitoxin RelB.
Expression of the cytotoxin RelE inhibits translation in the cells, due to its ability to cleave mRNA found in the A-site of the ribosome [2]. An indigenous factor for expression of RelE in E. coli is conditioned by amino acid starvation [2].
[1] Gotfredsen M, Gerdes K. The Escherichia coli relBE genes belong to a new toxin-antitoxin gene family.
[2] Pedersen K, Zavialov AV, Pavlov MY, Elf J, Gerdes K, Ehrenberg M. The bacterial toxin RelE displays codon-specific cleavage of mRNAs in the ribosomal A site.
Sequence and Features
RBS and double terminator are added the RelE gene.
