Fig. 4From: Dissecting the essential role of N-glycosylation in catalytic performance of xanthan lyaseThree-dimensional structure of EcXly visualized by PyMOL. a Secondary structures of EcXly: α-helix (red); β-sheet (yellow); random coil (green). b The structural alignment between EcXly (green) and PXL (cyan). The catalytic residues were shown in blue sphere and the glycosylation site was shown in magenta sphere. c Structural elements around the active sites. Tryptophan residues were colored in blue. The catalytic residues were colored in red rod. The glycosylation site N599 was highlighted in green rod. The picture in the black box was a close-up view of the catalytic residues of EcXlyBack to article page
