- Abstract
- Full-length copies of cDNAs of the rpc19+ and rpc40+ genes encoding the common subunits of nuclear RNA polymerases I and III and the corresponding fragments of chromosomes were isolated from genomic and cDNA libraries of Schizosaccharomyces pombe and characterized. It was established that the cloned genes are located on chromosomes III and II of the fission yeast, respectively. The rpc40+ gene lacks introns, and the rpc19+ gene contains two intervening sequences. The comparison of subunits Rpc19 (125 aa; M 13 722 Da; pI 4.51) and Rpc40 (348 aa; M 39 141 Da; pI 5.40) of Sz. pombe, whose characteristics were deduced from the sequences of their cDNAs, with the orthologous components of other eukaryotes allowed the most conserved structure-functional domains of these proteins to be identified.
