We have provided thousands of clients with high-quality custom sialic acid glycoengineering services. Our service will assist global clients to attain their goals in the shortest timeline.
Sialic acid glycoengineering is increasingly applied in the field of glycoscience and beyond. Chemically modified analogs of N-acetylmannosamine, the biological precursor of sialic acid, or sialic acid analogs can be introduced into the metabolic sialic acid biosynthesis pathway resulting in their incorporation into sialoglycans.
N-Acetylglucosamine (GlcNAc) plays important structural roles at the surface of a wide range of cells from bacteria to humans. It is a component of bacterial cell wall peptidoglycan, fungal cell wall chitin, and also glycosaminoglycans and other polymers on the surface of animal cells. Animal cells and plants also use GlcNAc for cell signaling but do so in a different manner. In these multicellular organisms, intracellular levels of UDP-GlcNAc are used as sensors of nutritional status that result in protein modification by attachment of O-GlcNAc. Global O-GlcNAc modification of proteins has also been shown to be elevated when cells are subjected to a variety of cellular injuries including heat stress, oxidative stress, hypoxia, ischemia-reperfusion, and trauma hemorrhage and additionally in several different types of cancers. Finally, several lines of evidence point toward O-GlcNAc playing a key role in neuronal function and neurodegeneration. For example, O-GlcNAc is enriched at synapses, and mice with neuron-specific deletion of OGT display locomotor defects before neonatal death. In addition, components of proteinaceous aggregates found in neurodegenerative diseases, including the microtubuleassociated protein tau and α-synuclein, are modified with O-GlcNAc, and reduced levels of O-GlcNAc have been observed in Alzheimer's disease.
