A	Serine-tRNA ligase (archaeal) M-CSA #885	Serine-tRNA ligase (EC:6.1.1.11) exists as monomer and belongs to class IIa [PMID: 7540217]. The serine-tRNA ligases from a few of the archaea that belong to this group are different from the set of mutually more closely related serine-tRNA ligases from eubacteria, eukaryotes, and other archaea (IPR002317).
