• mutant phenotype: Specifically important in carbon source Heparin sodium salt from porcine intestinal mucosa; carbon source Chondroitin sulfate A sodium salt from bovine trachea; and perhaps carbon source hyaluronic acid. Belongs to the galactose mutarotase-like domain superfamily, which are thought to be carbohydrate-binding proteins (see InterPro IPR011013). Also, this family (PF16153) is predicted by the PFam curators to bind carbohydrates because of its conserved proximity to glycosyl hydrolyase family 88.
• Functional genetics of human gut commensal Bacteroides thetaiotaomicron reveals metabolic requirements for growth across environments

  • “...), suggesting that BT4410 and BT4411 function together in HA catabolism. Finally, we found that BT3233 was important for growth on the following 3 GAGs: CS (mean fitness, 1.6), HA (mean fitness, 0.7), and heparin (mean fitness, 2.2) ( Figure 3G ). BT3233 is a member...”
  • “...binding domains (galactose mutarotase-like domain, InterPro IPR011013) ( Mitchell et al., 2019 ). Homologs of BT3233 are mostly confined to Bacteroides species, including a number of human commensals. Using an archived transposon mutant, we confirmed that BT3233 is important for growth on CS ( Figure 3H...”

PLH7_FORAG / T2KN67 Uncharacterized protein P7; Polysaccharide utilization locus H protein P7; PUL H protein P7 from Formosa agariphila (strain DSM 15362 / KCTC 12365 / LMG 23005 / KMM 3901 / M-2Alg 35-1) (see paper)

• function: May be involved in ulvan degradation (Probable). Ulvan is the main polysaccharide component of the Ulvales (green seaweed) cell wall. It is composed of disaccharide building blocks comprising 3-sulfated rhamnose (Rha3S) linked to D-glucuronic acid (GlcA), L-iduronic acid (IduA), or D-xylose (Xyl) (Probable).
