We have determined the complete nucleotide sequence of a 39 648 bp segment, contained in cosmid c32F12, derived from the right arm of chromosome II from the fission yeast Schizosaccharomyces pombe. Computer analysis of the sequence revealed the presence of 15 non-overlapping open reading-frames (ORF

✦ Synopsis
We have analysed two new genes, YBR1007 and YBR1015, discovered during the systematic sequencing of chromosome II of S. cerevisiae. YBR1007 shows strong similarities to amino-acid permeases, in particular the high-affinity proline permeases of S. cerevisiae and A. nidulans. The number and position of the predicted membrane-spanning domains suggest a conserved structure for these proteins, with 12 trans-membrane domains. YBR1015 shows strong similarities to serine carboxypeptidases; all three residues of the "catalytic triad" typical of this family of enzymes are conserved in the YBR1015 protein. In a preliminary functional analysis we have created a null allele of the YBR1015 gene, and shown that it is not essential for cellular viability.

We report the sequence of a 8061 bp fragment of Saccharomyces cerevisiae chromosome VII. Five open reading frames (ORFs) of at least 100 amino acids were identified. Three show similarities to the amino-acid sequence of known gene products. ORF G9374 corresponds to the gene coding for the yTAF II 14
