Dynamics of the Heat Stress Response of Ceramides with Different Fatty-Acyl Chain Lengths in Baker’s Yeast
Fig 4
Trends in ceramide synthase activities.
The upper panel shows ceramide synthase activities toward DHC, while the lower panel shows ceramide synthase activities toward PHC. The X-axis represents the 30 minutes of heat stress and the Y-axis represents fold changes in activities. In each plot, the blue and gray dots represent averaged and individual enzyme activities, respectively. The yellow and green shading marks similar enzyme activity patterns involved in DHC (top panel) and PHC (bottom panel) synthesis, respectively. It is unknown whether the concentrations of fatty acyl CoAs remain constant during the experiment. If they change dynamically, the shown trends refer to the combined changes in fatty acyl CoAs and ceramide synthase activities.
