== Function == | |||
[https://www.uniprot.org/uniprot/HIPA_SHEON HIPA_SHEON] Toxic component of a type II toxin-antitoxin (TA) system; overexpression in wild-type temporarily inhibits cell growth, overexpression in a hipAB deletion leads to acute growth inhibition. The toxic effect of HipA is neutralized by its cognate antitoxin HipB. In the ternary phosphoserine-HipA-HipB-DNA complex the DNA is bent about 125 degrees; all HipA in the crystallized ternary complex is phosphorylated. In E.coli phosphorylation of HipA is thought to release HipB from the HipA-HipB-DNA complex, suggesting the complex functions differently in the 2 bacteria (PubMed:25056321). Phosphorylates Glu-tRNA-ligase (GltX, on 'Ser-239') in vivo, with HipB probably acts as a corepressor for transcription of the hipBA promoter (By similarity).[UniProtKB:P23874]<ref>PMID:25056321</ref> | |||
