Figure 2. Figure 2. Overall view of the (α/α)[6] barrel of endoglucanase CelA. (a) Side view of CelA showing the active-site cleft at the N-terminal end of the inner helices. The 12 α helices forming the barrel involve residues Gln52–Arg70, Ser94–Cys106, Gln110–Lys121, Thr151–Trp168, Tyr176–Cys191, Pro218–Thr228, Arg232–Val247, Tyr282–Phe293, Gln296–Ala310, Ala334–Ala343, Leu350–Ala362 and Tyr372–Ile384 (as defined by PROCHECK [35]). (b) Stereo Cα trace of CelA, viewed along the barrel axis. Amino acid positions are labeled every 20 residues. Figure 2. Overall view of the (α/α)[6] barrel of endoglucanase CelA.
