Function-related positioning of the type II secretion ATPase of Xanthomonas campestris pv. campestris. [PDF]
Gram-negative bacteria use the type II secretion (T2S) system to secrete exoproteins for attacking animal or plant cells or to obtain nutrients from the environment. The system is unique in helping folded proteins traverse the outer membrane.

All motors have to decide is what to do with the DNA that is given them
DNA translocases are a diverse group of molecular motors responsible for a wide variety of cellular functions. The goal of this review is to identify common aspects in the mechanisms for how these enzymes couple the binding and hydrolysis of ATP to their

Molecular basis of mEAK7-mediated human V-ATPase regulation
Structural basis of V-ATPase regulation by endogenous proteins is unclear. Here, the authors find mEAK7 as an endogenous V-ATPase modulator and determine its structure with V-ATPase, suggesting the potential role of mEAK7 in V-ATPase regulation.

Reciprocal Regulation of V-ATPase and Glycolytic Pathway Elements in Health and Disease
The ability of cells to adapt to fluctuations in glucose availability is crucial for their survival and involves the vacuolar proton-translocating ATPase (V-ATPase), a proton pump found in all eukaryotes.

Bacterial rotary export ATPases are allosterically regulated by the nucleotide second messenger cyclic-di-GMP [PDF]
The widespread second messenger molecule cyclic di-GMP (cdG) regulates the transition from motile and virulent lifestyles to sessile, biofilm-forming ones in a wide range of bacteria. Many pathogenic and commensal bacterial-host interactions are known to

Uncoupling of p97 ATPase activity has a dominant negative effect on protein extraction [PDF]
p97 is a highly abundant, homohexameric AAA+ ATPase that performs a variety of essential cellular functions. Characterized as a ubiquitin-selective chaperone, p97 recognizes proteins conjugated to K48-linked polyubiquitin chains and promotes their ...

Mitochondrial F(1)-ATPase contains a hexamer of alternating alpha and beta subunits. The assembly of this structure requires two specialized chaperones, Atp11p and Atp12p, that bind transiently to beta and alpha. In the absence of Atp11p and Atp12p, the hexamer is not formed, and alpha and beta precipitate as large insoluble aggregates.
