Abstract 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.
