DNA sequence analysis of a 35 kb segment from Saccharomyces cerevisiae chromosome VII reveals 19 open reading frames including RAD54, ACE1/CUP2, PMR1, RCK1, AMS1 and CAL1/CDC43.
We present DNA sequence data from a 35,364 bp region on the left arm of chromosome VII of Saccharomyces cerevisiae. This region contains 19 open reading frames (ORFs). ORF G1821 corresponds to the RAD54 gene involved in repair and recombination (Emery et al., 1991). G1810 is identical to the ACE1 gene sequenced by Szczypka and Thiele (1989), required for copper-inducible transcription of the CUP1 gene. The first 693 bp on the minus strand represent part of the 3' non-coding region from the P-type ATPase gene PMR1, previously sequenced by Rudolph et al. (1989), which is identical to the SSC1 gene (Smith et al., 1988). G1845 corresponds to the RCK1 protein kinase gene from S. cerevisiae (Dahlkvist and Sunnerhagen, 1994). G1861 is almost identical to the alpha-mannosidase gene AMS1 reported by Yoshihisa and Anraku (1989) and G1864 has 100% identity with the yeast CAL1 gene (Ohya et al., 1989)/CDC43 gene (Johnson et al., 1990) which is involved in control of cell polarity. This region also contains a gene specifying a Leu-tRNA precursor and a remnant of a tau element. ORF G1880 shows some similarity to the S. cerevisiae SNF2, STH1 and NPS1 genes and to the human ERCC1 gene. A 93 bp region shows similarity to yeast EST sequenced by Burns et al. (1994). None of the remaining ORFs has similarity to any sequence within the databases screened.
