Fig. 2From: Metagenomic insights into the diversity of carbohydrate-degrading enzymes in the yak fecal microbial communitySequence conservation of carbohydrate-active enzymes encoded in the yak fecal metagenome. The distribution of the percentage sequence identity between the annotated CAZymes and the best hits in the NCBI NR protein database is displayed by the box-plot (a) and pie-chart (b), respectively. The proteins allocated to six functional classes (i.e. GHs, GTs, PLs, CEs, CMBs, AAs) of CAZymes are separately shown. The percentage identity intervals are illustrated by the gradient of colorBack to article page
