Class c: Alpha and beta proteins (a/b) [51349] (147 folds) |
Fold c.116: alpha/beta knot [75216] (1 superfamily) core: 3 layers: a/b/a, parallel beta-sheet of 5 strands, order 21435; contains a deep trefoil knot |
Superfamily c.116.1: alpha/beta knot [75217] (9 families) known or predicted SAM-dependent methytransferases including the SPOUT 'sequence' superfamily all known members have dimeric structures |
c.116.1.1: SpoU-like RNA 2'-O ribose methyltransferase [75218] (5 proteins) contains extra strand (3) in the parallel beta-sheet, order 321546 |
c.116.1.2: Hypothetical protein MTH1 (MT0001), dimerisation domain [75221] (1 protein) contains extra strand (3) in the parallel beta-sheet, order 321546; interrupted by an insert OB-fold domain |
c.116.1.3: YbeA-like [82371] (5 proteins) Pfam PF02590 |
c.116.1.4: tRNA(m1G37)-methyltransferase TrmD [89629] (2 proteins) fold and dimerisation mode are similar to those of the YbeA-like family; contains additional C-terminal all-alpha subdomain |
c.116.1.5: YggJ C-terminal domain-like [89632] (4 proteins) contains extra strand (3) in the parallel beta-sheet, order 321546; similar dimerisation to the MTH1 domain |
c.116.1.6: EMG1/NEP1-like [159513] (3 proteins) Pfam PF03587; structurally most similar to the AF1056-like family, but more decorated |
c.116.1.7: AF1056-like [159518] (2 proteins) Pfam PF04013; DUF358 |
c.116.1.8: AF0751-like [159523] (1 protein) Pfam PF01994; DUF127 |
c.116.1.0: automated matches [191557] (1 protein) not a true family |
