Long alpha-hairpin (46556)
2 helices; antiparallel hairpin, left-handed twist
Superfamily
formerly a class II aminoacyl-tRNA synthetase N-domain Superfamily
similar structure to L29p (scop_sf 46561); contains extra short helix; forms homodimer: an open bundle Superfamily
forms 'fan'-like heterooligomers, in which the domains of different subunit make similar interactions at the tip of the hairpin Superfamily
forms homodimer: an open bundle, different from the TRAM dimer Superfamily
Type III secretion system needle Superfamily
