摘要
Structures and properties of the recently found aspartate-specific cell death-related plant proteases called phytaspases are reviewed and compared to those of caspases, animal apoptotic proteases. Caspases (cysteine-dependent proteases) and phytaspases (serine-dependent proteases) dramatically differ in structure, although manifest a similar substrate specificity and a play a similar role in the programmed cell death. Distinctions in the structural organization of animal and plant death proteases were shown to define differences in the regulation strategies of functioning of these proteolytic enzymes in the two kingdoms.
