Structural Classification of Proteins

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]
