Gill genome bins and un-binned contigs for carbohydrate active enzymes (CAZymes).
A) Proportion of GH domains according to the substrate specificity at gills.bin1 and gills.bin 4 binned genomes and at other un-binned contigs from gills metagenome dataset. Substrate specificities as previously defined [9]: dark green = cellulose/xylan GH families (5, 6, 8, 9, 10, 11, 12, 44, 45, 51, 52, 62, and 74); dark blue = GH families with other or not-unique specificities (1, 2, 3, 13, 15, 23, 27, 30, 31, 35, 39, 43, 73, 77, 78, 79, 94, 95, 103, 108, 109, 115, 128, 130); light grey = laminarin GH families (16 and 81); yellow = other plant cell wall polysaccharides GH families (26, 53, and 67); light blue = chitin GH families (18, 19, and 20); light green = peptidoglycan GH families (28 and 105). B) Novel multicatalytic CAZymes configurations detected on Teredinibacter sp. gills.bin.4 genome bin (labeled in black), and on un-binned contigs from gill-symbiotic gammaproteobacterial community (labeled in red). Abbreviations key: glycoside hydrolases (GH), carbohydrate esterases (CE), carbohydrate binding modules (CBM). Catalytic domains and binding modules are color coded as black squares and gray circles.
