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         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}.
