TABLE 3.

Distribution of glycosyl hydrolase homologs (according to BLASTP) of upregulated proteins identified by ABPP or comparative proteomics during growth on xylan in Thermococcus sp. strain 2319x1E in other members of the Thermococcales.

Enzymes with proposed function in xylan hydrolysis are highlighted in gray.

*Xylanolytic activity for the GT35 homolog was reported only for T. zilligii (Uhl and Daniel, 1999), however, as previously suggested (Rolland et al., 2002) and in accordance with our studies, the enzyme possesses glycogen phosphorylase activity (Supplementary Figure 7 in Supplementary Data Sheet 1).
