Investigation of xylan degradation in Thermococcus sp. 2319x1E

Thermococcus sp. 2319x1E is able to grow on different mono- or polysaccharides as carbon source, including xylan. To investigate xylan degradation in Thermococcus sp. 2319x1E, cells were grown on 4 different carbon sources for 12 h (mid-exponential phase) and harvested by centrifugation. Using a label-free quantification approach the whole proteomes were analyzed. In another experiment a glycosidase specific activity-based probe (JJB384) was used to isolate specific Thermococcus glycosidases activated during growth on xylan or xylose.
