Dear Mamuna Mukhtar

what do you mean that your protein does not have an alpha elix? Do you mean any alpha elix? or that it miss a trasmembrane helix that could be necessary to anchor your protein outside the cell surface?

Because the are proteins in nature that has B-barrel folding (eg. bacteiral outer membrane proteins). But of course it depends from the specific nature of your protein. I do not think that with out know more information about your proteim we can provide you any reilable tips.

best regards
