Family: Methionyl-tRNA synthetase (MetRS), Zn-domain

in the Pyrococcus abyssi MetRS structure there is a tandem repeat of two such domains swapped with their zinc-binding 'knuckles', this duplicated finger occupies a larger region (124-183) than defined below; there is a structurally equivalent region in the E. coli enzyme lacking the second zinc-binding site

Lineage:

1. Root: scop
2. Class: Small proteins [56992]
   Usually dominated by metal ligand, heme, and/or disulfide bridges
3. Fold: Rubredoxin-like [57769]
   metal(zinc or iron)-bound fold; sequence contains two CX(n)C motifs, in most cases n = 2
4. Superfamily: Methionyl-tRNA synthetase (MetRS), Zn-domain [57770]
   uperfamily
5. Family: Methionyl-tRNA synthetase (MetRS), Zn-domain [57771]
   in the Pyrococcus abyssi MetRS structure there is a tandem repeat of two such domains swapped with their zinc-binding 'knuckles', this duplicated finger occupies a larger region (124-183) than defined below; there is a structurally equivalent region in the E. coli enzyme lacking the second zinc-binding site

Protein Domains:

1. Methionyl-tRNA synthetase (MetRS), Zn-domain [57772]
   1. Escherichia coli [TaxId: 562] [57773] (9)
   2. Pyrococcus abyssi [TaxId: 29292] [111451] (1)
      SQ Q9V011 1-606; C-domain 616-722 is solved separately: 1MKH
