Functional reconstitution of beta-glucan elicitor-binding activity upon incorporation into lipid vesicles.

abstract：:The effect of removal of Ca2+ bound to thrombospondin (TSP) on the protein structure in solution has been investigated using ESR spin-label techniques. A maleimide spin label was selectively attached to the free thiol group presumably near the carboxyl-terminal domain in which Ca2+-binding sites are situated. The ESR ...
