Source: InterPro

Description

IPR023457 is a Methionine-tRNA synthetase, type 2.

<p>Methionine-tRNA ligase ([ec:6.1.1.10]) is an alpha 2 dimer. In some species (archaea, eubacteria and eukaryotes) a coding sequence, similar to the C-terminal end of MetRS, is present as an independent gene which is a tRNA binding domain as a dimer. In eubacteria, MetRS can also be split in two sub-classes corresponding to the presence of one or two CXXC domains specific to zinc binding. The crystal structures of a number of methionine-tRNA ligases are known [[cite:PUB00006477], [cite:PUB00006254], [cite:PUB00006518]].</p> <p>This entry represents type 2 methionine-tRNA synthetase from eubacteria. Subfamily 2a links one zinc ion whereas subfamily 2b does not [[cite:PUB00068784]].</p>
