The region of Saccharomyces cerevisiae chromosome III centromere-distal to the PGK gene is the site of frequent chromosome polymorphisms. We have sequenced this region from fragments of chromosome III isolated from three different yeast strains, GRF88, CN31C and CF4-16B. The sequence analysis demonstrates that these polymorphisms are associated with the… (More)
The incidence of human infections by the fungal pathogen Candida species has been increasing in recent years. Enolase is an essential protein in fungal metabolism. Sequence data is available for human and a number of medically important fungal species. An understanding of the structural and functional features of fungal enolases may provide the structural… (More)
Research into the mode of action of the essential oil of Melaleuca alternifolia (Tea tree oil) is briefly reviewed. Its mode of action is interpreted in terms of the membrane-toxicity of its monoterpenoid components and different approaches for determining cell membrane damage are discussed.
The Ty transposable elements of Saccharomyces cerevisiae form a heterogeneous family within which two broad structural classes (I and II) exist. The two classes differ by two large substitutions and many restriction sites. We show that, like class I elements a class II element, Tyl-17, also appears to contain at least two major protein coding regions,… (More)
Primer extension analysis has been used to study the principal H4 mRNAs present at different developmental stages and in several adult tissues of Xenopus borealis and X. laevis. In X. borealis a single sequence class predominates in oocytes, tadpoles and cultured fibroblasts. There is also a polymorphic minor type which shows no developmental regulation.… (More)
