Organisms Yeast

The abundance of many protein kinases in cells is an indication of the great importance of protein phosphorylation in cellular regulation. Exactly 113 protein kinase genes have been recognized in yeast, and it is estimated that the human genome encodes more than 1000 different protein kinases. Tyrosine kinases (protein kinases that phosphorylate Tyr residues) occur only in multicellular organisms (yeast has no tyrosine kinases). Tyrosine kinases are components of signaling pathways involved in cell-cell communication (see Chapter 34). 

RDM provides the best results with mRNAs that are highly expressed, preferably from their own promoter. We observed a decrease in the quality of the results when using reporter mRNAs (e.g., GFP and luciferase) that are not native to the organism (yeast, in our case). The decrease in quality was apparent in the northern analyses, in which multiple bands or smears were observed. This is probably due to inefficient processing of these exogenous transcripts. 

The engineering of eukaryotic genes in eukaryotic organisms (yeast) is still in its infancy and its application is not as well developed as that of the bacterial systems. This is due to the increased complexity encountered in the structure and function of eukaryotic chromosomes. However, many advances have been made in the development of this system, particularly for the production of materials that require post-translational modification of the protein, and where other additional materials must be added before a fully functional molecule is produced (e.g. glycoproteins).

As a single-cell organism, a yeast cell is not polar in an organ sense, apical versus basolateral, for example, as is the case of intestinal epithelial cells. As a free-living organism, yeast accumulates nutrients for future use in times of nutrient depletion. Thus, little copper or iron is secreted from the yeast cell. On the other hand, yeast must have a mechanism to mobilize and use stored nutrients. Iron is stored in Sa. cerevisiae in a vesicular compartment, perhaps a (the) vacuole, most likely as an Fe(III) polyphosphate (Raguzzi et al., 1988). This iron phosphate is probably not significandy different... 

The analysis of inhibitor resistant mutants of model organisms (yeast, Rhodobacter) was used immediately after the sequence of cytochrome b had been established to identify those parts of die protein that are involved in the interaction with inhibitors and, possibly, quinone. This approach led to models of the structure of cytochrome b that were in generally good agreement with the X-ray structure, e.g., [26,28,29].
