Telomeres (Greek telos, end ) are sequences at the ends of eukaryotic chromosomes that help stabilize the chromosome. The best-characterized telomeres are those of the simpler eukaryotes. Yeast telomeres end with about 100 bp of imprecisely repeated sequences of the form... 

When using common E. coli expression system, recombinant allergens are present, either soluble in the supernatant of the cell lysate, or the proteins aggregate and form poorly soluble inclusion bodies. Inclusion bodies have to be solubilized under denaturing conditions (e.g., urea, guanidine-HCl treatment) and the protein has to be carefully refolded (Rea et al. 2004). One advantage of a eukaryotic yeast expression system is that yeast cells can segregate the expressed protein into the culture medium and thus can easily be purified. 

Ubiquitin is highly conserved in eukaryotes yeast and human ubiquitin differ at only 3 of 76 residues. The carboxyl-terminal glycine residue of ubiquitin (Ub) becomes covalently attached to the e-amino groups of several lysine residues on a protein destined to be degraded. The energy for the formation of these isopeptide bonds (iso because e- rather than a-amino groups are targeted) comes from ATP hydrolysis. 

Nevertheless, the first eukaryotic (yeast and human) genes encoding... 

Since, unlike higher eukaryotes, yeast and other lower eukaryotes have the shikimate pathway, they can synthesize Q from chorismate (4) by the prephenate (9) —> 4-hydroxyphenylpynivate pathway (10) or by the tyrosine (12) 4-hydroxyphenylpynivate pathway (10) (Figure 12), similar to those prokaryotes that lack the gene encoding CPL (the homolog of E. coli ubiC).

A recent study has examined the reaction between Cr(VI) and plasma cell membranes in parental (ergosterol-producing, 33 erg ) and mutant (ergosterol-free, erg-2) strains of an eukaryotic yeast, C. albicans (218). In the absence of Cr(VI), the plasma membrane from the erg-2 strain showed greater rigidity than...
