Orc5p is a subunit of the origin recognition complex in the budding yeast Saccharomyces cerevisiae, which has been shown to play a critical role in both chromosomal DNA replication and transcriptional silencing. We have cloned cDNAs from both human and fission yeast Schizosaccharomyces pombe that encode proteins homologous to the budding yeast and(More)
Replication protein A (RPA) is a three-subunit protein complex with multiple functions in DNA replication. Previous study indicated that human RPA (h-RPA) could not be replaced by Schizosaccharomyces pombe RPA (sp-RPA) in simian virus 40 (SV40) replication, suggesting that h-RPA may have a specific function in SV40 DNA replication. To understand the(More)
We have purified a single-stranded DNA-binding protein (SSB) from Schizosaccharomyces pombe (Sp) and have shown that it is composed of three subunits of 68, 30, and 12 kDa. The SpSSB supports T antigen-dependent unwinding of SV40 ori containing DNA, but is not functional in the SV40 in vitro replication reaction. All three genes that encode the SpSSB(More)
We constructed a plasmid that expresses FLO11 encoding a cell surface glycoprotein of Saccharomyces cerevisiae under the control of a constitutive promoter. This plasmid conferred pellicle-forming ability on the non-pellicle-forming industrial strain of S. cerevisiae at the air-liquid interface of the glucose-containing liquid medium. The induced(More)
