title: Two genes encoding ribosomal protein L3 of Schizosaccharomyces pombe and their proximal promoter regions.
abstract: We have cloned and sequenced two genes, rpl3-1 and rpl3-2, encoding the ribosomal protein L3 of Schizosaccharomyces pombe. The two genes contain an open reading frame encoding 388 amino acids (aa) with a M(r) of 43,808. The aa sequences are identical, except at position 78, where Rpl3-1 displays a valine residue and Rpl3-2 contains isoleucine. The aa sequences show 75% identity to the RPL3 aa sequence from Saccharomyces cerevisiae. S1-nuclease protection analysis revealed that both genes are transcribed. The promoter sequences of the two rpl3 genes are significantly different, but both promoters contain the conserved homol-D element. Transcription starts between 40 and 50 nt downstream from this element.
