HepT: a RNase like toxin

HepT is a toxin that can be effectively inhibited the growth of bacteria.The HepT toxin could function as an RNase with a RX4-6H active motif and cleave mRNA to inhibit cell growth. Complete with HepT (HZAU-China 2021:BBa_K3733010) was used in this study.

Usage and Biology

As an RNase enzyme, HepT can degrade mRNA at the transcriptional level, which ultimately leads to cell death
