Q91_0021 | Glycyl-tRNA synthetase beta subunit. (161 aa) | ||||
glyQ | Glycyl-tRNA synthetase alpha subunit. (326 aa) | ||||
metG | Methionyl-tRNA synthetase, class Ia; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation. (677 aa) | ||||
proS | Prolyl-tRNA synthetase, family II; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and i [...] (570 aa) | ||||
tyrS | Tyrosyl-tRNA synthetase, class Ib; Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two- step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr); Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 2 subfamily. (400 aa) | ||||
aspS | Aspartyl-tRNA synthetase; Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn); Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily. (595 aa) | ||||
valS | Valyl-tRNA synthetase, class Ia; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 1 subfamily. (874 aa) | ||||
ileS | Isoleucyl-tRNA synthetase; 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). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 1 subfamily. (937 aa) | ||||
hisS | Histidyl-tRNA synthetase. (421 aa) | ||||
thrS | Threonyl-tRNA synthetase, class IIa; Catalyzes the attachment of threonine to tRNA(Thr) in a two- step reaction: L-threonine is first activated by ATP to form Thr-AMP and then transferred to the acceptor end of tRNA(Thr). (639 aa) | ||||
pheS | Phenylalanyl-tRNA synthetase, alpha subunit; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily. (339 aa) | ||||
pheT | Phenylalanyl-tRNA synthetase beta chain; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily. (792 aa) | ||||
gltX | Glutamyl-tRNA synthetase 1; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu). (472 aa) | ||||
leuS | Leucyl-tRNA synthetase, class Ia; Belongs to the class-I aminoacyl-tRNA synthetase family. (816 aa) | ||||
argS | Arginyl-tRNA synthetase. (585 aa) |
