Lengths of 3/10 helices (b, e) and flanking coil regions (a, c, d, f) situated between beta strand and alpha helix (a, b, c) and between alpha helix and beta strand (d, e, f). For connecting bridges between beta strands and alpha helices: BCI is a region of coil between beta strand and 3/10 helix; BIH is a 3/10 helix between beta strand and alpha helix; ICH is a region of coil between 3/10 helix and alpha helix. For connecting bridges between alpha helices and beta strands: HCI is a region of coil between alpha helix and 3/10 helix; HIB is a 3/10 helix between alpha helix and beta strand; ICB is a region of coil between 3/10 helix and beta strand.
