Schematic of arabinoxylan showing chemical structure and proposed A. acidocaldarius strain DSM 446 genes annotated to produce enzymes catalyzing hydrolysis of specific bonds in the xylan backbone as well as functional groups attached to the backbone. See Tables 2 and 3 for description of gene products. GH family numbers listed are known to demonstrate common genes associated with hydrolysis of representative bonds, but they do not take into account increased specificity of other enzymes that may hydrolyze these bonds also
