CD BioGlyco has extensive experience in customized DNA-encoded glycan libraries (DEGLs) and has helped to study various glycobiological studies such as Glycan-protein Interactions, and bacterial enzymes involved in glycan biosynthesis through High-throughput Screening of DEGLs. Bacteria contain a variety of glycans, such as peptidoglycan. Enzymes involved in their biosynthesis are a rich source of targets for novel antibacterial agents. We provide a professional and customized DEGL screening service for bacterial enzyme research, helping to screen inhibitors of bacterial enzymes by designing and constructing DEGLs to support the development and optimization of antimicrobial substances. Besides, we also help to analyze the binding specificity of bacterial enzymes, glycan recognition, targets for bacterial infection intervention, etc.
Based on our leading synthetic capabilities and experienced team, we provide customized solutions, including DEGLs tailored to specific bacterial enzymes, DEGL screening, Data Analysis, and Hit Validation and Assessment. The specific experimental steps are as follows:
We design DEGLs for various bacterial enzyme targets, taking into account the natural substrates of the enzyme, potential binding targets, complexity of glycans, etc.
We custom-sterilize libraries of various orders of magnitude according to our clients' bacterial enzyme research needs. Each glycan structure is conjugated to a unique DNA tag, which serves as a unique identifier for the glycan and is used to track and identify glycan interactions with bacterial enzymes.
The constructed DEGL is used to screen high-affinity molecules against bacterial enzymes in a high-throughput manner, including affinity-based screening. This process includes the incubation of bacterial enzymes with DEGL, washing, amplification, and sequencing.
We analyze screening data using efficient bioinformatics tools and data processing algorithms with high data processing speed. Based on our leading synthetic capabilities, de-DNA compounds are also synthesized and their biological activities are validated through binding studies, structural analyses, and more. We help screen bacterial enzyme inhibitors efficiently and provide support for the development of effective treatments for bacterial infections.
After understanding our clients' experimental needs, we customize DEGL screening protocols to help find effective bacterial enzyme inhibitors and other studies.
Technology: DNA coding library (DEL) screening
Journal: Bioorganic & Medicinal Chemistry Letters

Results: In this study, affinity selection of target proteins was performed using the DELopen platform to find inhibitors of the bacterial enzymes UDP-N-acetylglucosamine-enolpyruvyl transferase (MurA) and d-alanine ligase B (DdlB). The researchers immobilized His-tagged enzymes on magnetic beads and incubated them with DELopen libraries. Five DdlB binders and two MurA binders were ultimately screened by sequencing and decoding. To determine which parts of the initial hit compounds were critical for inhibitory potency, the researchers performed a hit deconstruction campaign and found that two deconstructed analogs displayed antimicrobial activity. This study provides data to support the development and structure optimization of antimicrobial agents.
