Abnormalities of glycosphingolipids in mucopolysaccharidosis type III B.

Journal of Lipid Research, 1984
Glycosphingolipids from brain, liver, and spleen of a patient with mucopolysaccharidosis type III B were quantitatively analyzed. Neutral glycosphingolipids containing glucosylceramide, lactosylceramide, globotriaosylceramide, globotetraosylceramide, and

The biosynthesis of cytidine 5'-monophospho-n-acetylneuraminic acid by an enzyme from Neisseria meningitidis.

Journal of Biological Chemistry, 1962
In the accompanying paper (2) it was shown that Neisseria meningitidis, strain 1908 (Group C), forms N-acetylneuraminic acid by the condensation of N-acetyl-n-mannosamine and phosphoenolpyruvate with elimination of the phosphate group.

Methods for Improving Settlement and Metamorphosis of Shelled Marine Mollusks in Aquaculture: A Review

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Settlement and metamorphosis are key developmental hurdles in marine mollusk aquaculture. Environmental signals (such as biofilms, algae, and signals from conspecifics) and biochemical pathways (including nitric oxide, thyroid hormones, catecholamines, and GABA) regulate the transition of larvae into benthic juveniles. Combining ecological observations

Absence of Neu5Gc and Presence of Anti-Neu5Gc Antibodies in Humans-An Evolutionary Perspective. [PDF]

, 2019
The glycocalyx of human cells differs from that of many other mammals by the lack of the sialic acid N-glycolylneuraminic acid (Neu5Gc) and increased abundance of its precursor N-acetylneuraminic acid (Neu5Ac).

The Japanese Macaque as a Diabetes Recipient Animal Model for Porcine Islet Xenotransplantation

MedComm, Volume 7, Issue 4, April 2026.
Porcine islet xenotransplantation is effective for severe diabetes; however, preclinical studies are essential. In this study, we evaluated the suitability of the Japanese macaque as a recipient model for islet xenotransplantation, including identifying the preferred method to induce diabetes.

Isolation and characterization of a trisialoganglioside from mouse brain, containing 9-O-acetyl-N-acetylneuraminic acid.

Journal of Biological Chemistry, 1980
A new ganglioside, containing an alkali-labile linkage, was extracted from mouse brain and purified. It represents 5.2% of total lipid-bound sialic acid in the tissue and was obtained in pure form with a yield of about 50%.

Overexpression of Escherichia coli yaiX Confers Multidrug Resistance and Enhances Virulence in the Silkworm Infection Model

Microbiology and Immunology, Volume 70, Issue 4, Page 193-205, April 2026.
ABSTRACT The emergence of bacteria with both antimicrobial resistance and high virulence has become a global health concern, underscoring the urgent need to elucidate the molecular basis underlying these traits. Here, we employed the silkworm (Bombyx mori) infection model, which is suitable for high‐throughput screening, together with an Escherichia ...

Transglycosylation Capabilities of Wild‐Type α‐l‐Fucosidase iso1 from Paenibacillus thiaminolyticus and Its Engineered Mutants: Preparation of Fucosylated Oligosaccharides

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Several point mutations were introduced into the α‐l‐fucosidase iso1 from Paenibacillus thiaminolyticus (α‐l‐f1Pth‐wt) to enhance its transfucosylation activity. The S237V variant (α‐l‐f1Pth‐S237V) demonstrated superior regioselectivity in the synthesis of 3′‐and 6′‐fucosyllactose and functionalized 3′‐fucosyllactose bearing a Boc‐protected ...

Sialic acid acquisition in bacteria - one substrate many transporters [PDF]

, 2016
The sialic acids are a family of 9-carbon sugar acids found predominantly on the cell-surface glycans of humans and other animals within the Deuterostomes and are also used in the biology of a wide range of bacteria that often live in association with ...

Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Here we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...
