pro·te·a·some

 (prō′tē-ə-sōm′)
n.
A cellular protein complex consisting of proteolytic enzymes that degrade endogenous proteins, especially those that are damaged, pathogenic, or no longer of use.

[Alteration of earlier prosome (influenced by protease) : pro(grammed), from the earlier belief that proteasomes played a role in regulating messenger RNA translation + -some.]
