topA | DNA topoisomerase I; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA- (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supe [...] (599 aa) | ||||
pheT | Phenylalanyl-tRNA synthetase beta chain; Belongs to the phenylalanyl-tRNA synthetase beta subunit family. Type 1 subfamily. (803 aa) | ||||
pheS | Phenylalanyl-tRNA synthetase alpha chain; Belongs to the class-II aminoacyl-tRNA synthetase family. Phe-tRNA synthetase alpha subunit type 1 subfamily. (341 aa) | ||||
lysU | Lysyl-tRNA synthetase; Belongs to the class-II aminoacyl-tRNA synthetase family. (497 aa) | ||||
tyrS | Tyrosyl-tRNA synthetase; 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 1 subfamily. (417 aa) | ||||
serS | Seryl-tRNA synthetase; Catalyzes the attachment of serine to tRNA(Ser). Is also able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L- seryl-tRNA(Sec), which will be further converted into selenocysteinyl- tRNA(Sec). (423 aa) | ||||
asnS | Asparaginyl-tRNA synthetase. (465 aa) | ||||
glnS | glutaminyl-tRNA synthetase. (540 aa) | ||||
pyrH | Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP. (241 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. (912 aa) | ||||
hisS | Histidyl-tRNA synthetase. (423 aa) | ||||
aspS | Aspartyl-tRNA synthetase; Catalyzes the attachment of L-aspartate to tRNA(Asp) in a two-step reaction: L-aspartate is first activated by ATP to form Asp- AMP and then transferred to the acceptor end of tRNA(Asp). Belongs to the class-II aminoacyl-tRNA synthetase family. Type 1 subfamily. (574 aa) | ||||
lig | NAD-dependent DNA ligase; DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double- stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA. (659 aa) | ||||
glyQS | Glycyl-tRNA synthetase. (452 aa) | ||||
gltX | Glutamyl-tRNA synthetase; 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); Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily. (444 aa) | ||||
cysS | Cysteinyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family. (438 aa) | ||||
valS | Probable cation transport ATPase (similar to MgtA), fragment; 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. (863 aa) | ||||
metG | Methiony-tRNA synthetase. (517 aa) | ||||
proS | Prolyl-tRNA synthetase; 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). (473 aa) | ||||
argS | Arginyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family. (565 aa) | ||||
leuS | Leucyl-tRNA synthetase; Belongs to the class-I aminoacyl-tRNA synthetase family. (811 aa) | ||||
ATP_00459 | Predicted outer surface lipoprotein. (732 aa) |
