ATP hydrolysis tunes specificity of a AAA+ protease. [PDF]

open access: yesCell Rep, 2022
SummaryIn bacteria, AAA+ proteases such as Lon and ClpXP degrade substrates with exquisite specificity. These machines capture the energy of ATP hydrolysis to power unfolding and degradation of target substrates. Here, we show that a mutation in the ATP binding site of ClpX shifts protease specificity to promote degradation of normally Lon-restricted ...

ATPase and protease domain movements in the bacterial AAA+ protease FtsH are driven by thermal fluctuations [PDF]

open access: yesJournal of Molecular Biology, 2018
AAA+ proteases are essential players in cellular pathways of protein degradation. Elucidating their conformational behavior is key for understanding their reaction mechanism and, importantly, for elaborating our understanding of mutation-induced protease

Cryo-EM structure of the entire FtsH-HflKC AAA protease complex.

open access: yesCell Reports, 2022
The membrane-bound AAA protease FtsH is the key player controlling protein quality in bacteria. Two single-pass membrane proteins, HflK and HflC, interact with FtsH to modulate its proteolytic activity. Here, we present structure of the entire FtsH-HflKC

Netrin‐1 attenuates cerebral ischemia/reperfusion injury by limiting mitochondrial ROS and Ca2+ levels via activation of AKT phosphorylation and mitochondrial m‐AAA protease AFG3L2

open access: yesThe FASEB Journal, 2023
Cerebral ischemia–reperfusion (I/R) injury as the consequence of revascularization after ischemic stroke is associated with mitochondrial dysfunction, oxidative stress, and neuron loss.

Crystal structure of the ATPase domain of the human AAA+ protein paraplegin/SPG7. [PDF]

open access: yesPLoS ONE, 2009
Paraplegin is an m-AAA protease of the mitochondrial inner membrane that is linked to hereditary spastic paraplegias. The gene encodes an FtsH-homology protease domain in tandem with an AAA+ homology ATPase domain.

Structures of the human LONP1 protease reveal regulatory steps involved in protease activation

open access: yesNature Communications, 2021
The human mitochondrial protease LONP1 is an AAA+ ATP-dependent quality control protease. Here, the authors present the cryo-EM structures of human LONP1 in three distinct states and provide insights into the mechanism and regulation of this important ...
