CC -!- FUNCTION: Probable antitoxin component of a putative type VII toxin-
CC antitoxin (TA) system. Neutralizes cognate toxic MJ1548 by di-
CC AMPylation. {ECO:0000250|UniProtKB:Q8ECH7}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-tyrosyl-[protein] = diphosphate + O-(5'-adenylyl)-L-
CC tyrosyl-[protein]; Xref=Rhea:RHEA:54288, Rhea:RHEA-COMP:10136,
CC Rhea:RHEA-COMP:13846, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:46858, ChEBI:CHEBI:83624; EC=2.7.7.n1;
CC Evidence={ECO:0000250|UniProtKB:Q8ECH7};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + O-(5'-adenylyl)-L-tyrosyl-[protein] = diphosphate + O-
CC [5'-(adenylyl-(5'->3')-adenylyl)]-L-tyrosyl-[protein];
CC Xref=Rhea:RHEA:66528, Rhea:RHEA-COMP:13846, Rhea:RHEA-COMP:17046,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:83624,
CC ChEBI:CHEBI:167160; Evidence={ECO:0000250|UniProtKB:Q8ECH7};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q8ECH7};
CC Note=Binds 2 Mg(2+) ions. {ECO:0000250|UniProtKB:Q8ECH7};
CC -!- SUBUNIT: Probably forms a complex with cognate toxin MJ1548.
CC {ECO:0000250|UniProtKB:Q8ECH7}.
CC -!- SIMILARITY: Belongs to the MntA antitoxin family. {ECO:0000305}.
