Cyanobacterial aminoacyl-tRNA synthetase, CAAD domain (IPR025564)

Short name: CAAD_dom

Domain relationships



This domain is present in aminoacyl-tRNA synthetases (aaRSs), enzymes that couple tRNAs to their cognate amino acids [PMID: 18775898]. aaRSs from cyanobacteria containing the CAAD (for cyanobacterial aminoacyl-tRNA synthetases appended domain) protein domains are localised in the thylakoid membrane. The domain bears two putative transmembrane helices and is present in glutamyl-, isoleucyl-, leucyl-, and valyl-tRNA synthetases, the latter of which has probably recruited the domain more than once during evolution.
