Protein

Isoleucine--tRNA ligase

Gene
ileS, SPJ_1554
Organism
Streptococcus pneumoniae (strain JJA)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile) By similarity.UniRule annotation

Catalytic activityi

ATP + L-isoleucine + tRNA(Ile) = AMP + diphosphate + L-isoleucyl-tRNA(Ile).UniRule annotation

Cofactori

Binds 1 zinc ion per subunit By similarity.UniRule annotation

Domaini

IleRS has two distinct active sites: one for aminoacylation and one for editing. The misactivated valine is translocated from the active site to the editing site, which sterically excludes the correctly activated isoleucine. The single editing site contains two valyl binding pockets, one specific for each substrate (Val-AMP or Val-tRNA(Ile)) By similarity.UniRule annotation
