    Notes: Summary The complete nucleotide sequence of the β-glucosidase gene of Kluyveromyces fragilis has been determined. This sequence contains an open reading frame of 2535 base pairs encoding a protein of 845 amino acids. Analysis of the transcription products revealed only one transcript of about 3 kb identical in both Kluyveromyces fragilis and in the expression host Saccharomyces cerevisiae. The protein molecular weight of 93,811 Kd deduced from the sequence is consistent with the 90,000 Kd determined by SDS polyacrylamide gel electrophoresis with the purified protein. Mapping of the starts of transcription shows that two starting points are used in the natural host Kluyveromyces fragilis. A comparison of the amino acid sequence with that of other β-glucosidases revealed three regions of homology. One of these regions contains an amino acid sequence very similar to a peptide isolated from the active site of β-glucosidase A3 from Aspergillus wentii and could be implicated in the catalytic mechanism of these glucolytic enzymes.

    Topics: Biology
    Notes: Summary Two vectors, termed pG63.11 (7.6 Kb) and pHCG3 (9.6 Kb), suitable for yeast transformation have been constructed. The pHCG3 vector has cosmid properties. Both vectors contain a single 3.3 Kb EcoRI-HindIII fragment of yeast origin which carries the yeast URA3 gene (1.1 Kb) and the origin of replication of the 2 µm plasmid (2.2 Kb). They confer ampicillin resistance and they contain 5 unique EcoRI,HpaI,HindIII,BamHI and SalI restriction sites. Cosmid pHCG3 was used to clone the nitrogen fixation (nif) gene cluster of Klebsiella pneumoniae carried by twoHindIII fragments of 17 and 26 Kb, respectively. The resulting cosmid, termed pGPC875 (53 Kb) which conferred a Nif+ phenotype to Escherichia coli, was introduced in yeast by transformation. No acetylene reduction activity was detectable in the transformants. However it was shown that the entire information for nitrogen fixation can be replicated and maintained intact in yeast for more than 50 generations of growth.

    Notes: Summary When the bI4 RNA maturase, encoded by the fourth intron of the mitochondrial cytochrome b gene of Saccharomyces cerevisiae, was expressed in Escherichia coli, formation of intra-chromosomal Lac+ recombinants was stimulated threefold. This “hyper-rec” phenotype was recA as well as recBCD dependent. The most active form of the bI4 maturase stimulated homologous recombination whereas splicing deficient mutants of bI4 maturase were either deficient in or unable to stimulate homologous recombination.

    PDR3, a new yeast regulatory gene, is homologous toPDR1 and controls the multidrug resistance phenomenon (1994)

    Topics: Biology
    Notes: Abstract TheSaccharomyces cerevisiae PDR3 gene, located near the centromere of chromosome II, has been completely sequenced and characterised. Mutationspdr3-1 andpdr3-2, which confer resistance to several antibiotics can be complemented by a wild-type allele of the PDR3 gene. The sequence of the wild-typePDR3 gene revealed the presence of a long open reading frame capable of encoding a 976-amino acid protein. The protein contains a single Zn(II)2Cys6 binuclear-type zinc finger homologous to the DNA-binding motifs of other transcriptional activators from lower eukaryotes. Evidence that the PDR3 protein is a transcriptional activator was provided by demonstrating that DNA-bound LexA-PDR3 fusion proteins stimulate expression of a nearby promoter containing LexA binding sites. The use of LexA-PDR3 fusions revealed that the protein contains two activation domains, one localised near the N-terminal, cysteine-rich domain and the other localised at the C-terminus. The salient feature of the PDR3 protein is its similarity to the protein coded byPDR1, a gene responsible forpleiotropicdrugresistance. The two proteins show 36% amino acid identity over their entire length and their zinc finger DNA-binding domains are highly conserved. The fact that the absence of both PDR1 and PDR3 (simultaneous disruption of the two genes) enhances multidrug sensitivity strongly suggests that the two transcriptional factors have closely related functions.

    Notes: The COR region, a gene cluster located on chromosome X of Saccharomyces cerevisiae and including genes CYC1, UTR1, UTR3, OSM1, tRNAGly and RAD7, was sequenced within the framework of the European Union genome systematic sequencing project. It was compared with previously published sequences to be found in GenBank under the acronym YSCCORA. While some of the discrepancies observed can be readily ascribed to polymorphism, others most probably result from sequencing errors. A revised version of the sequence of the COR cluster is given. The sequence has been deposited in the EMBL Data Library under Accession Number L26347.

    Notes: We have sequenced a 61,989 bp stretch located between genes RAD7 and FIP1 of Saccharomyces cerevisiae chromosome X. This stretch contains 36 open reading frames (ORFs) of at least 100 codons. Fourteen of these correspond to sequences previously published as HIT1, CDC8, YAP17, CBF1, NAT1, RPA12, CCT5, TOR1, RFC2, PEM2, CDC11, MIR1, STE18 and GRR1. The proteins deduced from four ORFs (YJR059w, YJR065c, YJR075w, YJR078w) have significant similarity to proteins of known function from yeast or other organisms, including S. cerevisiae serine/threonine-specific protein kinase, Schizosaccharomyces pombe Act2 protein, S. cerevisiae mannosyltransferase OCH1 protein and mouse indoleamine 2,3-dioxygenase, respectively. Four of the remaining 18 ORFs have similarity to proteins with unknown function, six are weakly similar to other known sequences, while another eight exhibit no similarity to any known sequence. In addition, three tRNA genes have been recognized. Three genes clustered within 22 kb (YJR059w, YJR061w and TOR1) have counterparts arranged within 15 kb on the left arm of chromosome XI. The sequence has been deposited in the Genome Sequence Data Base under Accession Number L47993.

    Notes: We have sequenced a 42,500 bp stretch located on chromosome X of Saccharomyces cerevisiae between the genes MET3 and CDC8. This stretch contains 24 open reading frames (ORFs) of at least 100 amino acids. Ten of these correspond to previously published sequences, whereas of the 14 remaining ORFs, only one, GTD892, has significant similarity to proteins from yeast or other organisms. It may belong to the family of ubiquitin-protein ligases and be involved in the ubiquitin-dependent proteolytic pathway. In addition, three tRNA genes were recognized, two of which had not been hitherto localized. The sequence has been deposited in the Genome Sequence Data Base under Accession Number L36344.

    Notes: Actin molecules are major cytoskeleton components of all eukaryotic cells. All conventional actins that have been identified so far are 374-376 amino acids in size and exhibit at least 70% amino acid sequence identity when compared with one another. In the yeast Saccharomyces cerevisiae, one conventional actin gene ACT1 and three so-called actin-related genes, ACT2, ACT3 and ACT5, have been identified. We report here the discovery of a new actin-related gene in this organism, which we have named ACT4. The deduced protein, Act4, of 449 amino acids, exhibits only 33·4%, 26·7%, 23·4% and 29·2% identity to Act1, Act2, Act3 and Act5, respectively. In contrast, it is 68·4% identical to the product of the Schizosaccharomyces pombe Act2 gene and has a similar level of identity to other Sch. pombe Act2 homologues. This places Act4 in the Arp3 family of actin-related proteins. ACT4 gene disruption and tetrad analysis demonstrate that this gene is essential for the vegetative growth of yeast cells. The act4 mutants exhibit heterogenous morphological phenotypes. We hypothesize that Act4 may have multiple roles in the cell cycle. The sequence has been deposited in the Genome Sequence Data Base under Accession Number L37111.

    Notes: This paper reports the DNA sequence of a segment of 9·8 kb of the chromosome III. The sequenced DNA contains the MATα locus. The new sequence of the MATα locus differs from the previously reported sequence by six modifications in the W segment. We have found the same modifications in the HML locus. The corrected sequence contains, in HML, an open reading frame (ORF) of 190 codons which ends at the border between the W segment and the flanking DNA. In the MAT locus, this ORF extends in the flanking DNA up to 538 codons. This ORF corresponds to a gene independently identified as BUD5 (Chant et al., 1991). This gene presents homologies with the exchange factors SDC25 and CDC25. A large ORF of 1399 codons is found on the opposite side of MATα (toward the telomere). This ORF corresponds to a new gene YCR724. Next to this gene is a small ORF, YCR725, of 127 codons. The localization of this fragment on chromosome III, originally supposed to be distal from the MAT locus based on genetic distance, illustrates variation in recombination frequency along the chromosome and suggests the existence of hot spots of recombination between MAT and the THR4 locus.
