Streptomyces RNases – Function and impact on antibiotic synthesis
Frontiers in Microbiology, 2023 Streptomyces are soil dwelling bacteria that are notable for their ability to sporulate and to produce antibiotics and other secondary metabolites. Antibiotic biosynthesis is controlled by a variety of complex regulatory networks, involving activators ...

Molecular Microbiology, Volume 120, Issue 6, Page 874-892, December 2023., 2023 New functions for endoribonuclease III were unravelled in the facultative photosynthetic bacterium Rhodobacter sphaeroides by transcriptome analysis and phenotypic screening under three different growth conditions. The RNase III deficient mutant showed reduced pigmentation, linked to decreased expression of photosynthesis‐related mRNAs (bch and crt ...

A Novel Pathway of Functional microRNA Uptake and Mitochondria Delivery
Advanced Science, Volume 10, Issue 24, August 25, 2023., 2023 In the presence of serum, microRNAs (miRNAs) spontaneously form ≈110 nm nanoparticles, mediated bycationic proteins. When depleted, miRNA uptake is blocked. Unlike lysosome‐located, nanoparticle‐delivere mechanism are preferentially delivered to mitochondria of recipient cells by PNPT1.
