Protein Family Models

HicA_toxin is a bacterial family of toxins that act as mRNA interferases. The antitoxin that neutralises this is family HicB, Pfam:PF15919 [1,2,3]. [1]. 16895922.

type II toxin-antitoxin (TA) system HicA family toxin similar to Escherichia coli HicA, part of the HicA-HicB TA module that plays a role in inducing cleavage of mRNA and tmRNA (transfer-mRNA), thereby preventing translation; the hicAB locus is transcribed in response to amino acid and carbon starvation
