Significance of the CTP-binding motif for the interactions of S. coelicolor ParB with DNA, chromosome segregation and sporogenic hyphal growth.

Justyna Szymczak, Agnieszka Strzałka, Dominik Bania, Dagmara Jakimowicz, Marcin Jan Szafran

This study investigates the role of the CTP-binding GERR motif in S. coelicolor ParB's DNA binding, segrosome formation, and sporogenic hyphal growth.

The role of two major nucleoid associated proteins in Streptomyces, HupA and HupS, in stress survival and gene expression regulation

Agnieszka Strzałka, Jakub Mikołajczyk, Klaudia Kowalska, Michał Skurczyński, Neil A. Holmes, Dagmara Jakimowicz

This study investigates the roles of HupA and HupS in Streptomyces coelicolor growth, stress survival, and gene expression regulation, finding they act synergistically and as global transcription regulators.
