Functional domains of DEGs encoding carbohydrate transport proteins and surrounding CAZymes identified in xylan- or pectin-grown cultures. (A) MB2003 monoculture on xylan. (B) MB2003 coculture on xylan. (C) B316T monoculture on pectin. (D) B316T coculture on pectin. (E) MB2003 monoculture on pectin. (F) MB2003 coculture on pectin. *, CAZyme families of genes and DEGs (red) encoding polysaccharide-degrading enzymes colocalized with carbohydrate transport genes. SBP, solute-binding protein; PP, permease protein; AXE, acetyl-xylan esterase; ABP, ATP-binding protein; EPS, exopolysaccharide; TC system, two-component system histidine kinase; HAD family hydrolase, haloacid dehalogenase superfamily hydrolase. COG designations were as follows: COG0395, COG1175, COG1653, and COG1879, periplasmic component of ABC-type sugar transport system; COG1682, ABC-type polysaccharide/polyol phosphate export systems; COG2182, maltose-binding periplasmic proteins/domains; COG3833, permease component of ABC-type maltose transport systems; COG2211, Na+/melibiose symporter and related transporters; COG4213, periplasmic component of ABC-type xylose transport system; COG1129 and COG3839, ATPase component of ABC-type sugar transport systems; COG4209, permease component of ABC-type polysaccharide transport system; COG1172, permease component of ribose/xylose/arabinose/galactoside ABC-type transport systems.
