Fig. 1From: The xyl-doc gene cluster of Ruminiclostridium cellulolyticum encodes GH43- and GH62-α-l-arabinofuranosidases with complementary modes of actionOverall structure of the N-terminal part of the mature form of GH4310-1233. In gray, the ribbon representation of the GH43 module with the three catalytic amino-acids: in red, the catalytic aspartate D46; in purple, the aspartate “helper” D156; and in green, the catalytic glutamate E207. The X19 module is colored in yellowBack to article page
