What are guanosine triphosphate-binding proteins doing in mitochondria?
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1998 The discovery of GTP-binding proteins in mitochondria is a recent event. These regulatory proteins may be participating in membrane fusion and thereby playing important roles in the physiology of the mitochondrion. So far, it has been proposed that GTP-binding protein mediated membrane fusion may be involved in protein import, steroid hormone ...

Multiphasic interactions between nucleotides and target proteins [PDF]
arXiv, 2016 The nucleotides guanosine tetraphosphate (ppGpp) and guanosine pentaphosphate (pppGpp) bind to target proteins to promote bacterial survival (Corrigan et al. 2016). Thus, the binding of the nucleotides to RsgA, a GTPase, inhibits the hydrolysis of GTP.

Evolution of the bacterial nucleosidase PpnN and its relation to the stringent response
Microbial Cell, 2019 In our recent publication (Zhang et al., 2019), we demonstrate an interesting mode of regulation of purine metabolism unique to Proteobacteria. In this microreview, we would like to reflect on the ideas put forward, with special focus on protein domain ...

Sequence heterogeneity and the dynamics of molecular motors [PDF]
, 2005 The effect of sequence heterogeneity on the dynamics of molecular motors is reviewed and analyzed using a set of recently introduced lattice models. First, we review results for the influence of heterogenous tracks such as a single-strand of DNA or RNA on the dynamics of the motors.
