title: Crystal structure of the haemopexin-like C-terminal domain of gelatinase A.
abstract: The crystal structure of the haemopexin-like C-terminal domain of gelatinase A reveals that it is a four-bladed beta-propeller protein. The four blades are arranged around a channel-like opening in which Ca2+ and a Na-Cl+ ion pair are bound.
