Protein-carbohydrate interactions are involved in several cellular and biological functions. Integrating structure and function of carbohydrate-binding proteins with disease-causing mutations help to understand the molecular basis of diseases. Although databases are available for protein-carbohydrate complexes based on structure, binding affinity and function, no specific database for mutations in human carbohydrate-binding proteins is reported in the literature. We have developed a novel database, CarbDisMut, a comprehensive integrated resource for disease-causing mutations with sequence and structural features. It has 1.17 million disease-associated mutations and 38,636 neutral mutations from 7,187 human carbohydrate-binding proteins. The database is freely available at https://web.iitm.ac.in/bioinfo2/carbdismut. The web-site is implemented using HTML, PHP and JavaScript and supports recent versions of all major browsers, such as Firefox, Chrome and Opera.

Lectins are carbohydrate-binding proteins which play key roles in various biological processes, including cell signaling, pathogen recognition and development. Previous research conducted on ricin-B lectin domains and carbohydrate-binding modules of family 13 (CBM13) illustrated the striking resemblances between these two groups of protein domains. In this study, we report on the discovery, identification and putative biochemical characteristics of a ricin-B-like domain that is unique for GH27 enzymes from land plants, identified in the OsAPSE enzyme from Japanese rice (Oryza sativa L.

Galectins are a family of carbohydrate-binding proteins known to maintain intestinal microbiota homeostasis. Emerging evidence suggests that the bacterial symbiont plays a role in modulating insecticide resistance in insect. However, whether galectins influence insecticide susceptibility through microbiota regulation remains unclear.

Hyaluronic acid (HA), a linear glycosaminoglycan, serves as a key structural constituent of extracellular matrices, participating in diverse biological processes across both normal physiological and pathological contexts. While the gut microbiota exerts a pivotal influence on HA utilization within the human body, current scientific literature indicates a limited understanding of the molecular mechanisms underlying this interaction. In this study, a gut bacterium Enterococcus faecalis F1221 has been isolated, which demonstrated the ability to degrade HA.

Galectins are glycan-binding proteins (GBPs) characterized by conserved carbohydrate recognition domains (CRDs). Galectin-9, which contains two CRDs, regulates immune responses through interactions with glycoproteins. However, the full-length structure of galectin-9 remains unresolved.

Unlabelled: Microbial deconstruction of plant polysaccharides is important for environmental nutrient cycling, and bacteria proficient at this process have extensive suites of polysaccharide-specific enzymes. In the gram-negative saprophyte , genome annotation suggests that 17 genes are predicted to encode Carbohydrate-Active enZymes (CAZymes) with roles in cellulose degradation; however, previous work suggested that only a subset of these genes is essential. Building upon that work, here, we identify the required and minimally sufficient set of enzymes for complete degradation of cellulose using a combination of transcriptomics, gene deletion analysis, heterologous expression studies, and metabolite analysis.
