CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00805};
CC Note=Binds 1 Fe(2+) ion per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00805};
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Ribosomal frameshifting; Named isoforms=2;
CC Comment=The replicase 1a is produced from conventional translation of
CC the 1a ORF. The replicase 1ab is generated probably by a +1 ribosomal
CC frameshifting mechanism occurring at the 1a-1b genes boundary.;
CC Name=Replicase 1a;
