The single structure of this enzyme from Pyrococcus horikoshii (PDB-ID: 1irx), which is part of the dataset, does not contain any co-crystallized amino acid ligand. The numbers of protein-ligand complexes available for each aaRS are given in SI Appendix Fig. S2. For twelve aaRSs, protein...
The primary structure of a protein is the linear sequence of its amino acid (AA) units, starting from the amino-terminal residue (N-terminal) to the carboxyl-terminal residue (C-terminal). From: Emerging Trends in Computational Biology, Bioinformatics, and Systems Biology, 2015 ...
