Structural highlights
Function
MNTA_HAEIN Probable antitoxin component of a type VII toxin-antitoxin (TA) system. Neutralizes cognate toxic HEPN probably by di-AMPylation (Probable). A mixture of HepT and MntA binds nucleotides; the highest affinity is for TTP, ATP binds more tightly than ADP or AMP (PubMed:16028221).[1] [2]
