Fig. 1

Cladogram of Family GH11 (GH11 domain) sequences. Clusters depicted in blue, labeled 1, 2 and 3 include sequences that may correspond to xylanases active in alkaline conditions and high temperature. Clusters depicted in red contain sequences corresponding to acidophilic, thermoresistant xylanases. Color code of the sequence clusters corresponds to that used in Table 1 for the different domain architectures
