Sequence analysis of a 10.5 kb DNA fragment from the yeast chromosome VII reveals the presence of three new open reading frames and of a tRNAThr gene

We report the sequence analysis of a 10,531 bp DNA of Saccharomyces cerevisiae chromosome VII. This sequence contains five complete open reading frames (ORFs) potentially encoding proteins longer than 100 amino acids and incomplete ORF encoding for the 3' part of the GCN5 gene (Georgakopoulos a...

Description
Summary:We report the sequence analysis of a 10,531 bp DNA of Saccharomyces cerevisiae chromosome VII. This sequence contains five complete open reading frames (ORFs) potentially encoding proteins longer than 100 amino acids and incomplete ORF encoding 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 tRNAThr (TGT) is also present in position 6842-6913.
