The GE296_RS03820 and GE296_RS03830 genes are involved in capsular polysaccharide biosynthesis in Riemerella anatipestifer

The FASEB Journal, Volume 38, Issue 13, 15 July 2024.
The genes GE296_RS03820 and GE296_RS03830 in R. anatipestifer play crucial roles in CPS biosynthesis. Additionally, deletion mutants of these genes have demonstrated potential for cross‐protection and as live attenuated vaccines. Abstract Riemerella anatipestifer is a pathogenic bacterium that causes duck serositis and meningitis, leading to ...

Near-ultraviolet Excess in Slowly Accreting T Tauri Stars: Limits Imposed by Chromospheric Emission [PDF]

, 2011
Young stars surrounded by disks with very low mass accretion rates are likely in the final stages of inner disk evolution and therefore particularly interesting to study.

Development of a group II intron‐based genetic manipulation tool for Streptomyces

Microbial Biotechnology, Volume 17, Issue 5, May 2024.
In this work, the first efficient Streptomyces genomic manipulation tool is established based on the mobile group II intron Ll.LtrB. To enhance insertion efficiency and ensure ready‐to‐use in different Streptomyces strains, we incorporated RecX co‐expression into our design to repress the potential competition of RecA‐dependent homologous recombination.

THE PROTOPLANETARY DISK AROUND THE M4 STAR RECX 5: WITNESSING THE INFLUENCE OF PLANET FORMATION?

The Astrophysical Journal, 2010
We present Spitzer Space Telescope low-resolution spectroscopy of the protoplanetary disk around the M4 star RECX 5, a low-mass member of the approximate to 8 Myr old eta Chamaeleontis star cluster. Two features of the disk around RECX 5 set it apart from other young, low-mass stars with protoplanetary disks: its mineralogy and its disk geometry.

Effects of RecX proteins on the growth curves of cells expressing wild type RecA protein or RecA D112R protein.

, 2016
Cells containing pRecA Ec or pRecA [D112R] were grown in LB with Ampicillin 100mkg/ml. Where indicated, the cells contained plasmid pEAW847, expressing the RecX and RecA proteins from E.coli, pEAW858 –RecX and RecA D112R proteins from E.

Transcriptional and Mutational Analyses of theStreptomyces lividans recXGene and Its Interference with RecA Activity [PDF]

Journal of Bacteriology, 2000
ABSTRACTThe role of the 20,922-Da RecX protein and its interference with RecA activity were analyzed inStreptomyces lividans. TherecXgene is located 220 bp downstream ofrecA. Transcriptional analysis by reverse transcriptase PCR demonstrated thatrecXandrecAconstitute an operon. WhilerecAwas transcribed at a basal level even under noninducing conditions,
