Galactofuranosyl-containing glycopeptide of Penicillium charlesii. Vacuum ultraviolet circular dichroism.
The far and vacuum u.v. circular dichroism (CD) of peptidophosphogalactomannan from P. charlesii is reported to 182.5 nm in aqueous and aqueous/organic solvents, and to 150nm in films. CD of films of the peptide-free derivative is reported to 150 nm. On the basis of these data we conclude that the peptide chain is unordered, and may best be described as a hydrated coil showing some stiffness. The small observed saccharide CD may result from cancellation of contributions from the various saccharide structures present or from a lack of repeating secondary structure.
