It take it you are referring to the beta-alpha-beta motif?
I was looking for a complete makeup for many domains, such
as this one for the b-a-b as follows:
============================================================
Average length of the structural components of the bab unit:
------------------------------------------------------------
Beta-Sheet 5.5 (+- 1.8) *
Coil 5.3 (+- 4.9)
Alpha-Helix 11.9 (+- 3.2) *
Coil 4.6 (+- 3.4)
Beta-Sheet 5.2 (+- 1.5) *
Average fitting value 221 (+- 76), where the fitting value
is the product of the length of asterisked components.
(The fitting value cannot exceed 300).

Taylor & Thornton, J. Mol. Biol (1984) 173, 487-514.
