We report the sequence analysis of a 10 531 bp DNA fragment of Saccharomyces cerevisiae chromosome VII. This sequence contains five complete open reading frames (ORFs) potentially encoding proteins longer than 100 amino acids and an incomplete ORF coding for the 3′ part of the GCN5 gene (Georgakopoulos and Thireos, 1992). ORFs G9160 and G9155 correspond to the genes ENO1 (Holland et al ., 1981) and PUP2 (Gergatsou et al ., 1992) respectively. ORF G9165 codes for a protein which shares significant homology with known proteins present in databases (see below). The translated sequence of ORF G9170 shows 88% identity to the 6‐phosphogluconate dehydrogenase encoded by the gene 6PGD from S. cerevisiae present in the SwissProt data library (P38720). This indicates that G9170 might code for a second 6‐phosphogluconate dehydrogenase. ORF G9175 codes for a putative new member of the mitochondrial carrier family. A hypothetical tRNA Thr (TGT) is also present in position 6842–6913. The complete sequence has been entered in the EMBL data library under Accession Number U00028. © 1997 John Wiley & Sons, Ltd.
