  • Title: Photodynamic action on native and denatured transforming deoxyribonucleic acid from Haemophilus influenzae.
    Author: Ponce-De León M, Cabrera-Juárez E.
    Journal: J Bacteriol; 1970 Mar; 101(3):681-4. PubMed ID: 5309576.
    Abstract:
    The photodynamic inactivation of native or denatured transforming deoxyribonucleic acid (DNA) from Haemophilus influenzae is described. The inactivation at the same pH was higher for denatured than native DNA. At acidic pH, the inactivation both for native and denatured DNA was faster than at alkaline pH. The guanine content of photoinactivated native DNA at neutral pH was less than untreated DNA. The inactivation of biological activity was more extensive than the alteration of guanine. The absorption spectrum of photoinactivated native or denatured DNA was only slightly different than the control DNA at the different experimental conditions.
