 GatB_YqeyGatB domain | |
|---|---|
| SMART ACC: | SM000845 |
| Description: | This domain is found in GatB and proteins related to bacterial Yqey. It is about 140 amino acid residues long. This domain is found at the C terminus of GatB which transamidates Glu-tRNA to Gln-tRNA. The function of this domain is uncertain. It does however suggest that Yqey and its relatives have a role in tRNA metabolism. |
| InterPro ACC: | IPR018027 |
| InterPro abstract: | The GatB domain, the function of which is uncertain, is associated with aspartyl/glutamyl amidotransferase subunit B and glutamyl amidotransferase subunit E. These are involved in the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl-tRNA or glutaminyl-tRNA … expand |
| GO function: | carbon-nitrogen ligase activity, with glutamine as amido-N-donor (GO:0016884) |
