A quantum chemical study of an interaction between collagen fragments and calcium ions using calculations of model complexes

Abstract

© 2015 Springer Science+Business Media New York. Quantum chemical calculations revealed that the complexation between proline-containing collagen fragments and calcium ions involves a preferential interaction between Ca²⁺ ions and the oxygen and nitrogen atoms of proline in the glycine - proline - alanine fragment of the amino acid sequence of collagen.
