RESTRUCTURING SPACE ORDERING OF (DNA-PROTAMINE) COMPLEXES IN LIQUID-CRYSTALLINE DISPERSIONS UNDER PROTEOLYTIC-ENZYME TREATMENT
1995 (English)In: Liquid crystals (Print), ISSN 0267-8292, E-ISSN 1366-5855, Vol. 19, no 5, 595-602 p.Article in journal (Refereed) Published
Complexes of DNA with the protamines stellin A and stellin B, in polymer-containing solutions, form both liquid crystalline phases and liquid crystalline dispersions. The non-specific organization of the (DNA-protamine) phase is determined by the presence of protamine cross links between the DNA molecules and not by the inherent anisotropy (cholesteric) double-stranded DNA molecules. Elimination of these cross links by proteolytic enzyme action causes an increase in the distance between the DNA molecules which results in the appearance of an intense band in the CD spectrum and a fingerprint (cholesteric) texture.
