title: Galactofuranosyl-containing glycopeptide of Penicillium charlesii. Vacuum ultraviolet circular dichroism.
abstract: 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.
