HOK is the toxin of the HOK/SOK toxin-antitoxin system. The HOK/SOK is a type I toxin-antitoxin system originating from the R1 plasmid in E. coli. The SOK transcript can bind to a homologous region on HOK mRNA and prevent toxin expression. When E. coli undergoes cell division, the two daughter cells inherit the long-lived HOK toxin from the parent cell. Due to the short half-life of the SOK antitoxin, daughter cells inherit only small amounts and it is quickly degraded.

HOK - Toxin in Hok/Sok

HOK is the toxin of the HOK/SOK toxin-antitoxin system. The HOK/SOK is a type I toxin-antitoxin system originating from the R1 plasmid in E. coli. The SOK transcript can bind to a homologous region on HOK mRNA and prevent toxin expression. When E. coli undergoes cell division, the two daughter cells inherit the long-lived HOK toxin from the parent cell. Due to the short half-life of the SOK antitoxin, daughter cells inherit only small amounts and it is quickly degraded.

The gel electrophoresis of pSB1A3-HOK is shown in Figure 1. The result in lane 18 shows that HOK is present in the biobrick.
