Oligosaccharide side chains of human colonic mucins contain O-acetylated sialic acids and glycosulfate esters. Although these substituents are considered to protect the chains against degradation by bacterial glycosidases, sialate O-acetylesterase, N

A subset of normal human faecal bacteria composed of niucin oligosaccharide-degrading (MOD) strains appears to be the principal source of intraluminal, extracellular glycosidases degrading the oligosaccharides of gut mucin glycoproteins and epithelia

Publikováno v: The Journal of clinical investigation. 75(3)

We previously reported that the oligosaccharide chains of hog gastric mucin were degraded by unidentified subpopulations numbering approximately 1% of normal human fecal bacteria. Here we report on the enzyme-producing properties of five strains of m
