Description	Noncovalent interactions of poly(L-ly-sine) (PL), oligopeptides L-lysyl-L-alanyl-L-alanine and (L-lysyl-L-alanyl-L-alanine)2-- with meso-tetrakis(4-sulfonatophenyl)porphine (TPPS), and poly(L-glutamic acid) (PLGA) with meso-tetrakis(1-methyl-4-pyridyl)porphine tetra-p-tosylate (TMPyP) in aqueous solutions have been studied using combination of spectroscopic methods: Vibrational circular dichroism (VCD) spectroscopy in the mid-IR re-gion provides a direct informa-tion on conformational changes of the polypeptides and oligopeptides caused by interactions with porphyrins; UV-VIS absorption, fluorescence and electronic circular dichroism (ECD) reveal the aggregation characterization of the porphyrin part of the complexes. Interactions of TPPS with tripeptide, hexapeptide or PL containing about ten amino acid residues in the molecular chain are accompanied with the changes of VCD patterns in the amide I region. In these cases, conformation of the oligopeptide part of complexes is obviously influenced by i Noncovalent interactions of poly(L-ly-sine) (PL), oligopeptides L-lysyl-L-alanyl-L-alanine and (L-lysyl-L-alanyl-L-alanine)2-- with meso-tetrakis(4-sulfonatophenyl)porphine (TPPS), and poly(L-glutamic acid) (PLGA) with meso-tetrakis(1-methyl-4-pyridyl)porphine tetra-p-tosylate (TMPyP) in aqueous solutions have been studied using combination of spectroscopic methods: Vibrational circular dichroism (VCD) spectroscopy in the mid-IR re-gion provides a direct informa-tion on conformational changes of the polypeptides and oligopeptides caused by interactions with porphyrins; UV-VIS absorption, fluorescence and electronic circular dichroism (ECD) reveal the aggregation characterization of the porphyrin part of the complexes.
