Figure 2. Distribution of cellulose, hemicellulose, and lignin
degradation associated genes across selected genomes. (a) Distribution
of enzyme-encoding genes involved in cellulose, hemicellulose, and
lignin degradation pathways, as determined by KEGG database mapping. (b)
Cellulose degradation pathways showing cellulose degradation genes
encoding key enzymes. EC 3.2.1.74 and EC 3.2.1.91 were identified by
GH3, GH5, and GH8 in the CAZy database. (c) Carbohydrate-active enzyme
families involved in cellulose, hemicellulose, and lignin degradation
pathways determined via the CAZy database (GH: glycoside hydrolase, CE:
carbohydrate esterases, AA: auxiliary activities). Red text indicates
enzymes involved in lignin degradation, blue text indicates enzymes
involved in hemicellulose degradation, and black text indicates enzymes
involved in cellulose degradation.
