PFAM accession number:PF07973
Interpro abstract (IPR012947):

The catalytically active form of threonyl/alanyl tRNA synthetase is a dimer. Within the tRNA synthetase class II dimer, the bound tRNA interacts with both monomers making specific interactions with the catalytic domain, the C-terminal domain, and this SAD domain (the second additional domain). The second additional domain is comprised of a pair of perpendicularly orientated antiparallel beta sheets, of four and three strands, respectively, that surround a central alpha helix that forms the core of the domain [ (PUBMED:10319817) ].

GO process:tRNA aminoacylation (GO:0043039)
GO function:ATP binding (GO:0005524), aminoacyl-tRNA ligase activity (GO:0004812)
