Figure 1
Diagram of full-length xylanase Xys1L from S. halstedii showing its two domains and linker. Natural proteolysis of the cellulose-binding domain yields Xys1S. Engineered removal of both the cellulose-binding domain and the Gly-rich linker allowed the crystallization of the catalytic domain, the variant called Xys1Δ. The N-terminal residue of these three proteins corresponds to residue 46 of the ORF. |
