Microsoft se preocupa por tu privacidad Antonio Vercher: el fiscal que ayudó a construir la justicia ambiental en España

| MSN España
Sara Aagesen,Teresa Ribera,Rosa Aguilar,Elena Espinosa,Cristina Narbona La justicia ambiental en España pierde a una de sus figuras fundacionales. Con la muerte de Antonio Vercher desaparece no solo un jurista ejemplar, sino también un pionero que supo anticiparse a su tiempo y comprender que la defensa del medio ambiente debía ocupar un lugar central en el Estado de derecho. Su trayectoria deja una huella institucional duradera y constituye una herencia que merece reconocimiento y compromiso.

MatP local enrichment delays segregation independently of tetramer formation and septal anchoring in Vibrio cholerae

| BioRxiv
Abstract Vibrio cholerae harbours a primary chromosome derived from the monochromosomal ancestor of the Vibrionales (ChrI) and a secondary chromosome derived from a megaplasmid (ChrII). The coordinated segregation of the replication terminus of both chromosomes (TerI and TerII) determines when and where cell division occurs. ChrI encodes a homolog of Escherichia coli MatP, a protein that binds to a DNA motif (matS) that is overrepresented in replication termini.

MatP delays the segregation of chromosome termini independently of cell division and tetramer formation in Vibrio cholerae

|
By Elena Espinosa, Jihane Challita, Jean-Michel Desfontaines, Christophe Possoz
| BioRxiv
Abstract The cellular arrangement and segregation choreography of the genetic material is involved in the timing of assembly and cellular positioning of the cell division apparatus in bacteria. Key to this mode of regulation is the positioning of sister copies of the replication terminus zone (ter) of the chromosomes at the end of the replication cycle. The Vibrio cholerae genome is distributed on two chromosomes, ChrI and ChrII.
