h.4.15: Proline/betaine transporter ProP, C-terminal cytoplasmic domain [103661] (1 family) |
h.4.16: Fzo-like conserved region [111479] (1 family) antiparallel coiled-coil in the crystals |
h.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 |
