Fig. 1. Crystal structure of endoglucanase Cel12A from Rhodothermus marinus (PDB ID: 2BWA, chain A) with the β-jelly roll structure consisting of β-sheets (yellow), A (strands A1 to A6), and B (strands B1–B9). The alpha and 310 helices are colored in purple and blue, respectively. Two important catalytic residues (E124 and E207) are represented in green color using ball and stick model in the active site tunnel. The red colored bead close to the residue D106 on B5 strand indicates the center of mass (COM) of the protein.
