The actin regulatory protein, cofilin, increases the bending and twisting elasticity of actin
filaments and severs them. It has been proposed that filaments partially decorated with cofilin …

RNA helicase enzymes catalyze the in vivo folding and conformational re-arrangement of
RNA. DEAD-box proteins (DBPs) make up the largest family of RNA helicases and are found …

DEAD-box proteins are ATPase enzymes that destabilize and unwind duplex RNA. Quantitative
knowledge of the ATPase cycle parameters is critical for developing models of helicase …

DEAD-box RNA helicase proteins use the energy of ATP hydrolysis to drive the unwinding
of duplex RNA. However, the mechanism that couples ATP utilization to duplex RNA …

Plants acquire essential elements from inherently heterogeneous soils, in which phosphate
and iron availabilities vary. Consequently, plants have developed adaptive strategies to …

Mitochondria respond to environmental cues and stress conditions. Additionally, the disruption
of the mitochondrial network dynamics and its distribution is implicated in a variety of …

Mss116 is a Saccharomyces cerevisiae mitochondrial DEAD-box RNA helicase protein that
is essential for efficient in vivo splicing of all group I and group II introns and for activation of …

The role of the actin cytoskeleton in relation to mitochondria function and dynamics is only
recently beginning to be recognized. Myo19 is an actin-based motor that is bound to the outer …

Kinetic adaptation of muscle and non-muscle myosins plays a central role in defining the
unique cellular functions of these molecular motor enzymes. The unconventional vertebrate …

The JmjC-containing lysine demethylase, KDM4D, demethylates di-and tri-methylation of
histone H3 on lysine 9 (H3K9me3). How KDM4D is recruited to chromatin and recognizes its …
