Trypanosoma brucei is a single-celled parasitic protist that causes African sleeping sickness in people and nagana in cattle in sub-Saharan Africa. T. brucei and related trypanosomatid parasites contain an unusual catenated mitochondrial genome known as kinetoplast DNA (kDNA) composed of dozens of 23 kb maxicircles and thousands of 1 kb minicircles. The kDNA structure and replication mechanism are divergent from other eukaryotes and essential for parasite survival. POLIB is one of three Family A DNA polymerases that are independently essential to maintain the kDNA network, and has been implicated in minicircle replication. However, the division of labor among the paralogs, …

Positive-strand RNA viruses assemble numerous membrane-bound viral replicase complexes within large replication compartments to support their replication in infected cells. Yet the detailed mechanism of how given subcellular compartments are subverted by viruses is incompletely understood. Although, Tomato bushy stunt virus (TBSV) uses peroxisomal membranes for replication, in this paper, we show evidence that the ER-resident SNARE (soluble NSF attachment protein receptor) proteins play critical roles in the formation of active replicase complexes in yeast model host and in plants. Depletion of the syntaxin 18-like Ufe1 and Use1, which are components of the ER SNARE complex in the ERAS (ER …
