General Information

EC Number General Information Comment Organism
6.1.1.7 evolution the enzyme is constituted by three domains with an evolutionarily conserved modular arrangement: the N-terminal aminoacylation domain, the editing domain and the C-terminal domain (C-Ala). Alanyl-tRNA synthetases (AlaRSs) belong to class-II aminoacyl-tRNA synthetases Bizionia argentinensis
6.1.1.7 additional information the near complete NMR resonance assignment of the 122 amino acid C-Ala domain from Bizionia argentinensis is determined, enzyme structure homology modeling using the X-ray structure of Aquifex aeolicus AlaRS C-Ala domain Bizionia argentinensis
6.1.1.7 physiological function alanyl-tRNA synthetases (AlaRSs) play an essential role in the early events of protein synthesis by catalyzing the conjugation of amino acids to their cognate transfer RNAs. The C-terminal domain, C-Ala, plays an essential role in enzyme activity Bizionia argentinensis
