CC -!- FUNCTION: Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS
CC can inadvertently accommodate and process structurally similar amino
CC acids such as valine, to avoid such errors it has two additional
CC distinct tRNA(Ile)-dependent editing activities. One activity is
CC designated as 'pretransfer' editing and involves the hydrolysis of
CC activated Val-AMP. The other activity is designated 'posttransfer'
CC editing and involves deacylation of mischarged Val-tRNA(Ile).
CC {ECO:0000255|HAMAP-Rule:MF_02002}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-isoleucine + tRNA(Ile) = AMP + diphosphate + L-
CC isoleucyl-tRNA(Ile); Xref=Rhea:RHEA:11060, Rhea:RHEA-COMP:9666,

CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_02002};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_02002};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_02002}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02002}.
CC -!- DOMAIN: IleRS has two distinct active sites: one for aminoacylation and
CC one for editing. The misactivated valine is translocated from the
CC active site to the editing site, which sterically excludes the
CC correctly activated isoleucine. The single editing site contains two
CC valyl binding pockets, one specific for each substrate (Val-AMP or Val-
CC tRNA(Ile)). {ECO:0000255|HAMAP-Rule:MF_02002}.
CC -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC IleS type 1 subfamily. {ECO:0000255|HAMAP-Rule:MF_02002}.
