Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli
FEBS Open Bio, EarlyView.BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.

Chitosanase may enhance anti-fungal defense responses in transgenic tobacco [PDF]
, 2003 Chitosanase is an enzyme, similar to chitinase, capable of hydrolyzing the β-1,4-linkages between N-acetyl-D-glucosamine and D-glucosamine residues in partially acetylated chitosan polymers found in fungal cell walls.

Metal Complexes of D-Glucosamine and its Derivatives. VII. Metal Complexes of D-Glucosaminic Acid
Chemical and Pharmaceutical Bulletin, 1966 Stability constants, log K1 and log K2, of complexes of D-glucosaminic acid with Cu2+, Ni2+, Pb2+, Zn2+, Co2+, Cd2+, and Mn2+were determined by pH titration method. Copper complexes were found to be the most stable and the contribution of OH groups of glucosaminic acid to the complex formation was observed.

The hemostatic properties of chitosan in oral surgery
Biomedical and Biotechnology Research Journal, 2020 Chitosan (CS) belongs to the natural linear aminopolysaccharide family. It is formed by a repetition of D-glucosamine units (deacetylated units) and a smaller number of N-acetyl-D-glucosamine units. Their distribution is casual.
