Divergence and conservation of SUP2 (SUP35) gene of yeast Pichia pinus and Saccharomyces cerevisiae.

SUP2 (SUP35) is an omnipotent suppressor gene, coding for an EF-1 alpha-like protein factor, intimately involved in the control of translational accuracy in yeast Saccharomyces cerevisiae. In the present study a SUP2 gene analogue from yeast Pichia pinus was isolated by complementation of the temperature-sensitive sup2 mutation of S. cerevisiae.

[Development of a system of intragenic mapping for molecular genetic analysis of mutations in the gene LYS2 of Saccharomyces yeasts].

The collection of overlapping lys2 deletions (five in the chromosomal and seven in the plasmid LYS2 gene) is constructed in this work. The deletions overlap the whole coding region of the gene and provide the system for intragenic recombinational mapping of lys2 mutations in one of 14 controlled regions. A portion of these regions can be correlated with the regions on the physical map of LYS2.

[Mutational analysis of the starch utilization system in the yeast Saccharomyces cerevisiae].

Seven mutants of Saccharomyces cerevisiae deficient in production of extracellular glucoamylase have been analyzed. For each of the seven a monogenic pattern of inheriting the mutant phenotype has been observed. The mutations have been shown to map within five different genetic loci, three independent mutations affecting the STA2 locus and the other four residing in four formerly unidentified genes.
