Structural basis for Ca2+-dependent activation of a plant metacaspase

Plant metacaspases mediate immune response following activation by Ca2+. Here, via crystallography and functional analyses, the authors show that a linker domain in Arabidopsis Metacaspase 4 blocks substrate access to the active site but is cleaved multiple times in the presence of Ca2+ to allow enz...
