Harnessing the acceptor substrate promiscuity of Clostridium botulinum Maf glycosyltransferase to glyco-engineer mini-flagellin protein chimeras

open access: yesCommunications Biology
Several bacterial flagellins are O-glycosylated with nonulosonic acids on surface-exposed Serine/Threonine residues by Maf glycosyltransferases. The Clostridium botulinum Maf glycosyltransferase (CbMaf) displays considerable donor substrate promiscuity ...

Simultaneous ManNAc and Neu5Ac Quantification in Human Sera by LC-MS/MS

open access: yesInternational Journal of Molecular Sciences
N-Acetyl-D-mannosamine (ManNAc) and N-acetylneuraminic acid (Neu5Ac) are important components of glycosylation, affecting numerous physiologic processes. The effects of age, body mass index (BMI), race, or sex on serum levels of ManNAc and Neu5Ac are poorly understood. However, these associations are of substantial interest.

The Microbial Pathology of Neu5Ac and Gal Epitopes

Journal of Carbohydrate Chemistry, 2013
Glycans play a vital role in modulating many physiological and pathological phenomena of microbes and humans, such as bacterial adhesion, colonization, host-microbial interactions, cancer recognition, and blood group determination. The aim of the current review is to provide an account of the functions of N-acetyl sialic acid (Neu5Ac) and galactose ...
