Family: tRNA(m1G37)-methyltransferase TrmD

fold and dimerisation mode are similar to those of the YbeA-like family; contains additional C-terminal all-alpha subdomain

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]
    Mainly parallel beta sheets (beta-alpha-beta units)
  3. Fold: alpha/beta knot [75216]
    core: 3 layers: a/b/a, parallel beta-sheet of 5 strands, order 21435; contains a deep trefoil knot
  4. Superfamily: alpha/beta knot [75217]
    known or predicted SAM-dependent methytransferases including the SPOUT 'sequence' superfamily
    all known members have dimeric structures
