Examples for left-handed alpha-helices?

[Eckart Bindewald]

Hello!

Often it is cited, that left-handed alpha-helices are very rare in proteins, but DO exist. However,
I could not find a reference to an example structure. Who can inform me about a protein structure
which contains a left-handed alpha-helix (PDB codes preferred)?

Thank you very much,

Eckart Bindewald
