Autor: Janusz Rak, Haopeng Wang, Jerzy Leszczynski, Kit H. Bowen, Anna Szyperska, Xiang Li, Yeon Jae Ko

Publikováno v: ChemPhysChem. 11:880-888

The photoelectron spectrum of the anion of the guanine···cy- tosine base apair (GC)Cis recorded for the first time. The ob- served variation in the spectral peak-height ratios with the source conditions suggests the presence of two or more anionic

Valence Anions of 9-Methylguanine−1-Methylcytosine Complexes. Computational and Photoelectron Spectroscopy Studies

Autor: Jerzy Leszczynski, Yeon Jae Ko, Xiang Li, Anna Szyperska, Janusz Rak, Haopeng Wang, Kit H. Bowen

Publikováno v: Journal of the American Chemical Society. 131:2663-2669

The photoelectron spectrum for the radical anion of 9-methylguanine-1-methylcytosine, MGMC(-), was recorded for the first time. To interpret the experimental results, B3LYP/6-31++G(d,p) level computational studies were carried out for the neutral and

Theoretical studies on interactions between low energy electrons and protein-DNA fragments: valence anions of AT-amino acids side chain complexes

Autor: Janusz Rak, Kamil Mazurkiewicz, Agnieszka Gajewicz, Anna Szyperska, Jerzy Leszczynski

Publikováno v: Physical chemistry chemical physics : PCCP. 13(43)

Electron attachment to trimeric complexes that mimic most frequent hydrogen bonding interactions between an amino acid side chain (AASC) and the Watson-Crick (WC) 9-methyladenine-1-methylthymine (MAMT) base pair has been studied at the B3LYP/6-31++G(

[Interactions of aluminofluoride complexes (ALFx) with high-energy compounds (ADP, ATP) as revealed by molecular modeling]

Autor: Anna, Szyperska, Zygmunt, Machoy, Bogusław, Machaliński

Publikováno v: Annales Academiae Medicae Stetinensis. 52

Aluminofluoride complexes (AlFx) are toxic substances at the cellular and subcellular level, apparently implicated in degeneration of the nervous system. The present study focused on direct interactions with A1Fx of two common adenine nucleotides: ad
