Example Sentences:

(6) Circular dichroic studies and hydropathy profiling of the amino-acid sequence of this 'lac' permease suggest a secondary structure in which the polypeptide consists of 12 hydrophobic segments in alpha-helical conformation that traverse the membrane in zig-zag fashion connected by shorter, hydrophilic domains with most of the charged residues and many of the residues commonly found in beta-turns.
(7) Secondary structure prediction and analysis of far-ultraviolet circular dichroic spectra have revealed that G1 and G2 consist predominantly of beta-structure with a little alpha-helical content.

(11) Circular dichroic (CD) spectra showed that the normal protein and that activated by substitution of Ala59 to Thr59 are very similar in their overall structure.
(12) Even the most extensive carbamylation led to only marginal changes in the circular dichroic (CD) spectra of these substances and none in sedimentation coefficients studied.
