Abstract

Interactions of Ins(1,2,6)P-3 (IP), with spermine (Spm) and zinc cations have been studied by potentiometric and P-31 NMR titrations. In the 4-11 pH range, two IPSpmZn(2)H(3) and IPSpmZn(2)H mixed complexes are formed which are largely predominant with respect to the binary species. According to 31P NMR titration it is likely that one of the zinc cations preferably binds phosphates P1 and P6. The adduct formation between Ins(1,2,6)P-3 and spermine seems also favourable to the formation of the mixed complexes. The occurrence of ternary complexes involving inositol-phosphates, biogenic amines, and metallic cations may be of relevance in the regulation of biological processes. (C) 2001 Elsevier Science B.V.
