The Knock Out Yeast Strain YNL058C (A6) was unaffected by the 35% dilution of D2O. This also shows in the optical density results being about 0.4-0.5 OD 600.
This gene produced 44.54% of the amount of ethanol that the wild type produced.
INTERPERTATION In the graph and photos above, exposing this gene to 600 seconds of 400 Watt UV Light killed approximately 85% of yeast cell cultures, compared to its control counterpart, which was the same gene and amount of cells, just was not exposed to UV Light.
As part of the University of Wisconsin Stout Orphan Gene Project this gene was tested by exposing the cells to heat shock.
From the data gathered, there was a small negative effect to knocking out this gene when it came to the yeast's ability to hold up to heat shock. The modified yeast cells were only 83% as resistant to heat shock than the control.
As part of the University of Wisconsin Stout Orphan Gene Project this gene was tested by exposing the cells to 4mM of caffeine.
- BY4735(wild type yeast) and YNL058C(knockout yeast gene) growth after being subjected to 4mM caffeine solution following this protocol.
As seen in the growth curve, YNL058C shows no significant difference in growth sensitivity to caffeine. It is of note that from measurement 80 to measurement 250 there is a significant difference.
As part of the University of Wisconsin Stout Orphan Gene Project this gene was tested by exposing the cells to hydrogen peroxide.
BY4735 and YNL058C after being exposed to 0.065% dilution of hydrogen peroxide solution.
The growth curve for YNL058C suggests that the knockout had very little variation from wild type cells when exposed to hydrogen peroxide. The growth ceiling for the unstressed control was higher than wild type after 24 hours, suggesting the strain may have fast initial growth.
As part of the University of Wisconsin Stout Orphan Gene Project this gene was tested by exposing the cells to 1µg/ml Nystatin solution.
Based on the growth curves, we can see that the YNL058C control is growing at a faster rate than both the wild type control and the stressed wild type. However, the YNL058C being treated with Nystatin is growing at a slower rate than both wild type control and stressed wild type. This indicates that the removal of the YNL058C gene lessens the cells resistance to Nystatin.

The wild yeast cell treated with 3% formamide had a doubling time of 876.69 min. The 3% formamide solution added to nine transformed yeast cells was then compared to the wild yeast cell using the computed doubling times to see the effects of the formamide. In the experiment, some of the transformed yeast cells were heavily effected by the formamide, however, the YNL058C strain was one of the few not heavily effected- in comparison with the wild yeast cells. The YNL058C strain had doubling times slightly faster than the wild yeast cell, with a doubling time of 844.12 min. It can be concluded that the transformed yeast cell, YNL058C, did not have a unique response to the formamide stress test used in the experiment.
Transmembrane Domain GxxxG
The transmembrane domain of Ynl058cp shows homology with the SKG6/AXL2 alpha-helix transmembrane domain (IPR014805). In particular, this domain contains GaviG. The presence of a overlapping GxxxG motif  strongly indicates that Ynl058c dimerises.

As part of the University of Wisconsin Stout Orphan Gene Project this gene was tested by exposing the cells to 0.001% concentrated NLS. (Nonionic detergent)
-According to the graph above, we can see that the KO yeast cell YNL058C follow a smaller sensitivity to the stress than the Wild type strain.
-We can then conclude that the knocked-out gene in YNL058C doesn't have a significant impact on the growth of the yeast cell.
Knocked out gene seems to have very little effect on cell growth in pH 7 environment based on the flattening of the growth curve. Spikes in stressed line are to be ignored; they occurred due to clumping of cells during analysis. We are focusing on the general linear trend of the growth curve. Please see protocol for specific quantitative doubling time results.
The wild-type strain was used as a control in this experiment; no genes were knocked out, it just represents how the experiment ran on the knocked-out gene strains affects a "typical" cell growth curve. Inclusion of this data on each knock-out strain growth curve graph made for difficult interpretation, so it has been separated. Please refer to this graph as a control when viewing the knock-out strain growth curve graph. Spikes in stressed line are to be ignored; they occurred due to clumping of cells during analysis. We are focusing on the general linear trend of the growth curve.
