a
GH, glycoside hydrolase; CBM, carbohydrate binding module; PL, polysaccharide lyase; CE, carbohydrate esterase; GT, glycosyl transferase. Numbers of carbohydrate-active protein domains were retrieved from the CAZy database at http://www.cazy.org (13).
b
Indicates the total number of ORFs that contain either glycoside hydrolases, carbohydrate-binding modules, polysaccharide lyases, or carbohydrate esterases.
c
SigP, number of signal peptides.
d
CT, number of ATP binding cassette (ABC) carbohydrate transporters.
