The ParMRC system: molecular mechanisms of plasmid segregation by actin-like filaments

J Salje, P Gayathri, J Löwe - Nature Reviews Microbiology, 2010 - nature.com
The ParMRC plasmid partitioning apparatus is one of the best characterized systems for
bacterial DNA segregation. Bundles of actin-like filaments are used to push plasmids to …

[HTML][HTML] Exploring Spiroplasma biology: opportunities and challenges

S Harne, P Gayathri, L Béven - Frontiers in Microbiology, 2020 - frontiersin.org
Spiroplasmas are cell-wall-deficient helical bacteria belonging to the class Mollicutes. Their
ability to maintain a helical shape in the absence of cell wall and their motility in the absence …

[HTML][HTML] Filament organization of the bacterial actin MreB is dependent on the nucleotide state

…, N Mitra, SR Bagde, R Srinivasan, P Gayathri - Journal of Cell …, 2022 - rupress.org
MreB, the bacterial ancestor of eukaryotic actin, is responsible for shape in most rod-shaped
bacteria. Despite belonging to the actin family, the relevance of nucleotide-driven …

Effect of matrix cracking and material uncertainty on composite plates

P Gayathri, K Umesh, R Ganguli - Reliability Engineering & System Safety, 2010 - Elsevier
A laminated composite plate model based on first order shear deformation theory is
implemented using the finite element method. Matrix cracks are introduced into the finite element …

Nup358 binds to AGO proteins through its SUMO‐interacting motifs and promotes the association of target mRNA with miRISC

…, Y Ramtirtha, MS Madhusudhan, P Gayathri… - EMBO …, 2017 - embopress.org
Micro RNA (mi RNA )‐guided mRNA repression, mediated by the mi RNA ‐induced silencing
complex (mi RISC ), is an important component of post‐transcriptional gene silencing. …

[PDF][PDF] MreB5 is a determinant of rod-to-helical transition in the cell-wall-less bacterium Spiroplasma

…, S Duret, V Pande, M Bapat, L Béven, P Gayathri - Current Biology, 2020 - cell.com
In most rod-shaped bacteria, the spatial coordination of cell wall synthesis machinery by
MreBs is the main theme for shape determination and maintenance in cell-walled bacteria [1–9]. …

[HTML][HTML] Allosteric regulation of a prokaryotic small Ras-like GTPase contributes to cell polarity oscillations in bacterial motility

…, PR Gade, S Harne, J Herrou, T Mignot, P Gayathri - PLoS …, 2019 - journals.plos.org
Mutual gliding motility A (MglA), a small Ras-like GTPase; Mutual gliding motility B (MglB), its
GTPase activating protein (GAP); and Required for Motility Response Regulator (RomR), a …

[HTML][HTML] “Natively unfolded” VPg is essential for Sesbania mosaic virus serine protease activity

PS Satheshkumar, P Gayathri, K Prasad… - Journal of Biological …, 2005 - ASBMB
Polyprotein processing is a major strategy used by many plant and animal viruses to maximize
the number of protein products obtainable from a single open reading frame. In Sesbania …

[PDF][PDF] Motor activity dependent and independent functions of myosin II contribute to actomyosin ring assembly and contraction in Schizosaccharomyces pombe

…, R Hogg, M Sevugan, M Mishra, P Gayathri… - Current Biology, 2017 - cell.com
Cytokinesis depends on a contractile actomyosin ring in many eukaryotes [1–3]. Myosin II is
a key component of the actomyosin ring, although whether it functions as a motor or as an …

A distinct motif in a prokaryotic small Ras-Like GTPase highlights unifying features of walker B motifs in P-Loop NTPases

…, S Chakraborty, SS Shelke, P Gayathri - Journal of molecular …, 2020 - Elsevier
A hallmark of the catalytically essential Walker B motif of P-loop NTPases is the presence of
an acidic residue (aspartate/glutamate) for efficient Mg 2+ coordination. Although the Walker …
