Matrix-Monotonic Optimization for MIMO Systems [PDF]

, 2014
For MIMO systems, due to the deployment of multiple antennas at both the transmitter and the receiver, the design variables e.g., precoders, equalizers, training sequences, etc. are usually matrices.

Acinetobacter baumannii as a Model for the Study and Application of Gram‐Negative Outer Membrane Vesicles: A Systematic Review

Microbial Biotechnology, Volume 18, Issue 9, September 2025.
Investigation of outer membrane vesicles from Acinetobacter baumannii for potential biotechnological applications. ABSTRACT Outer membrane vesicles (OMVs) are extracellular nanostructures released from Gram‐negative bacteria. Acinetobacter baumannii OMVs (AbOMVs) have been extensively studied and can thus be used as a model for understanding multiple ...

Role of the Sinorhizobium meliloti Global Regulator Hfq in Gene Regulation and Symbiosis

Molecular Plant-Microbe Interactions, 2010
The RNA-binding protein Hfq is a global regulator which controls diverse cellular processes in bacteria. To begin understanding the role of Hfq in the Sinorhizobium meliloti–Medicago truncatula nitrogen-fixing symbiosis, we defined free-living and ...

Characterization of Aptamer-Protein Complexes by X-ray Crystallography and Alternative Approaches [PDF]

, 2012
Aptamers are oligonucleotide ligands, either RNA or ssDNA, selected for high-affinity binding to molecular targets, such as small organic molecules, proteins or whole microorganisms.

Archaeal protein containing domain of unknown function 2193 undergoes oligomeric reconfiguration upon iron–sulfur cluster binding

FEBS Letters, Volume 599, Issue 16, Page 2318-2333, August 2025.
This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Identification of the Hfq-binding site on DsrA RNA: Hfq binds without altering DsrA secondary structure [PDF]

RNA, 2003
DsrA RNA regulates the translation of two global regulatory proteins in Escherichia coli. DsrA activates the translation of RpoS while repressing the translation of H-NS. The RNA-binding protein Hfq is necessary for DsrA to function in vivo. Although Hfq binds to DsrA in vitro, the role of Hfq in DsrA-mediated regulation is not known.

Positive regulation by small RNAs and the role of Hfq [PDF]

Proceedings of the National Academy of Sciences, 2010
Bacterial small noncoding RNAs carry out both positive and negative regulation of gene expression by pairing with mRNAs; in Escherichia coli , this regulation often requires the RNA chaperone Hfq. Three small regulatory RNAs (sRNAs), DsrA, RprA, and ArcZ, positively regulate translation of the sigma factor RpoS ...

Interconnection of post-transcriptional regulation: The RNA-binding protein Hfq is a novel target of the Lon protease in Pseudomonas aeruginosa [PDF]

, 2015
Besides being a major opportunistic human pathogen, Pseudomonas aeruginosa can be found in a wide range of environments. This versatility is linked to complex regulation, which is achieved through the action of transcriptional regulators, and post ...

Phage‐mediated horizontal transfer of Salmonella enterica virulence genes with regulatory feedback from the host

iMeta, Volume 4, Issue 4, August 2025.
In this study, we found evidence of phage‐mediated horizontal transfer of virulence genes in Salmonella enterica in global habitats from a molecular evolutionary perspective. Notably, csrA, a global regulator in Salmonella enterica, curbed horizontal gene transfer by inhibiting the cyclization and release of prophage.

Functional Characterization of the RNA Chaperone Hfq in the Opportunistic Human Pathogen Stenotrophomonas maltophilia. [*Roscetto M, *Angrisano T, co-first authors]. [PDF]

, 2012
Hfq is an RNA-binding protein known to regulate a variety of cellular processes by interacting with small RNAs (sRNAs) and mRNAs in prokaryotes. Stenotrophomonas maltophilia is an important opportunistic pathogen affecting primarily hospitalized and ...
