Title:

Total chemical synthesis and X-ray structure of kaliotoxin by racemic protein crystallography.

Journal:

Chem Commun (Camb). 2010 Sep 28.

Abstract:

Here we report the total synthesis of kaliotoxin by 'one pot' native chemical ligation of three synthetic peptides. A racemic mixture of d- and l-kaliotoxin synthetic protein molecules gave crystals in the centrosymmetric space group P1[combining macron] that diffracted to atomic-resolution (0.95 A), enabling the X-ray structure of kaliotoxin to be determined by direct methods.
