Additional file 1 of Metagenomics-resolved genomics provides novel insights into chitin turnover, metabolic specialization, and niche partitioning in the octocoral microbiome
Additional file 1: Figure S1. Phylogenomic analysis of the Ca. Thioglobaceae family using SpeciesTreeBuilder v.01.0. Figure S2. COG functions (N=76) significantly enriched (q-value < 0.05) in the octocoral-derived Ca. Gorgonimonas (Endozoicomonadaceae) MAGs (N= 11, green), compared with all other MAGs (N=55) of this dataset. Figure S3. KEGG metabolic pathway map of the Ca. Gorgonimonas (Endozoicomonadaceae) MAGs of this study. Figure S4. Phylogeny of 101 full-length, bacterial endo-chitinase (EC 3.2.1.14) encoding genes, including the 11 endo-chitinase (GH18-family) genes from Endozoicomonadaceae MAGs (grey shadings) of this study. Figure S5. COG functions (N=34) significantly enriched (p-value < 0.05) in the Ca. Thioglobaceae MAGs (N= 6, dark green), compared with all other MAGs (N=60) of this dataset. An one-sided Welch’s t-test for unequal variances was performed in STAMP v.2.1.3. Multiple test correction was performed using the Benjamini-Hochberg correction (FDR). To further limit the displayed number of significant entries, an effect size filter was also applied, setting the “ratio of proportions” to 5.00. Figure S6. KEGG metabolic pathway map of the Ca. Thioglobaceae MAGs of this study. The metabolic map features glycolysis, pyruvate, nitrogen, sulfur, and taurine metabolism. EC numbers of enzymes catalyzing the reactions are given in rectangular boxes. EC numbers highlighted in green represent enzymes encoded on Ca. Thioglobaceae MAGs. Beige boxes indicate connections to other metabolic pathways active in these MAGs. Figure S7. KEGG carbon fixation map of Ca. Thiocorallibacter gorgonii MAG EG15H_Bin1 (Ca. Thioglobaceae). EC numbers of enzymes catalyzing the reactions are given in rectangular boxes. EC numbers highlighted in green represent enzymes encoded on this MAG. Beige boxes indicate connections to other metabolic pathways active in these MAGs. Orange dots highlight the substrates (Ribulose-1,5-bisphosphate, CO2, and H2O) and product (2 Glycerate-3-phosphate, 2 H+) of Rubisco (EC 4.1.1.39)
