 # PD-T4-10
+
+## Description
+The PD-T4-10 system is composed of 2 proteins: PD-T4-10_B and, PD-T4-10_A. This ORFs are overlapping and PD-T4-10_B is toxic while PD-T4-10_A neutralizes its toxicity, hinting to a toxin-antitoxin (TA) mechanism. It confers resitance to T2, T4, T6 and SECphi27 through an Abi defense mechanism :ref{doi=10.1038/s41564-022-01219-4}.
+
+## Molecular mechanism
+As far as we are aware, the molecular mechanism is unknown.

 ## Example of genomic structure
