antiparallel coiled-coil in the crystalsh.4.17: occludin/ELL-like [144292] (1 family)
antiparallel hairpin with a kinked second helix; similar to the N-terminal structure of the thermostable carboxypeptidase 1 (82731)
h.4.18: Gam-like [161266] (1 family)
homodimeric fold with a ring-like structure formed by kinked coiled-coil and a beta-ribboon, interrupted by small helical insertions
h.4.19: PspA lactotransferrin-binding region [161270] (1 family)
3 helices, the middle one is longer than the two others
