A Sperm–Plasma β-N-Acetyl-D-Hexosaminidase Interacting with a Chitinolytic β-N-Acetyl-D-Hexosaminidase in Insect Molting Fluid
Insects require molting fluids to shed the old cuticle during molting. β-N-acetyl-D-hexosaminidase, known as Hex1, together with various chitinases, is responsible for degrading the chitin component of the old cuticle. This study showed that another β-N-acetyl-D-hexosaminidase, termed OfHex3, interacted with Hex1 and functioned in the molting fluid, although the homolog of OfHex3 was known as a...
متن کاملRole of N-acetyl-β-d-hexosaminidase in cholesteatoma tissue
Cholesteatoma is a destructive disease characterized by the progressive expansion of keratinizing squamous epithelium in the middle ear and mastoid, and chronic inflammatory reaction of the subepithelial connective tissue. N-Acetyl-β-d-hexosaminidase (HEX) catalyzes the release of terminal non-reducing N-acetyl-d-hexosamine residues acting on glucosides and galactosides in glycoproteins, GM2-ga...
متن کاملStructural Insights into Cellulolytic and Chitinolytic Enzymes Revealing Crucial Residues of Insect β-N-acetyl-D-hexosaminidase
The chemical similarity of cellulose and chitin supports the idea that their corresponding hydrolytic enzymes would bind β-1,4-linked glucose residues in a similar manner. A structural and mutational analysis was performed for the plant cellulolytic enzyme BGlu1 from Oryza sativa and the insect chitinolytic enzyme OfHex1 from Ostrinia furnacalis. Although BGlu1 shows little amino-acid sequence ...
متن کاملActivity of N-acetyl-β-D-hexosaminidase in the saliva of children with type 1 diabetes.
BACKGROUND/AIM Type 1 diabetes is one of the most common chronic diseases in children. The aim of the study was to evaluate the catabolism of glycoconjugates in saliva of children with type 1 diabetes, by measurement of the activity of N-acetyl-β-D-hexosaminidase (HEX) in their saliva. MATERIAL/METHODS The study was performed in 65 children with type 1 diabetes and 39 healthy children. Saliva...
متن کاملN-acetyl-β-hexosaminidase in chronic tonsillitis and tonsillar hypertrophy.
BACKGROUND The concentration and specific activity of N-acetyl-β-hexosaminidase (HEX) in palatine tonsils with chronic tonsillitis and tonsillar hypertrophy give insight in tonsillar tissue remodeling and constitute a potential marker for diagnosis and treatment of chronic tonsillitis and tonsillar hypertrophy. AIM Determining the concentration and specific activity of N-acetyl-β-hexosaminida...
